As I exited the screening of Traitor, the terrorism thriller starring Don Cheadle that opens on Wednesday, I noticed something odd in the closing credits: story by Steve Martin and Jeffrey Nachmanoff. The second guy is the film's director. But that first guy ... Steve Martin? The Steve Martin?

I knew the one-time Wild and Crazy Guy was a renaissance man. In fact, lately I've enjoyed his writing, which is clever, nuanced, and intelligent, more than I've enjoyed most of his movies. He apparently is not as selective about his film projects as he is about his writing. His novella The Pleasure of My Company is one of my favorite recent books, and Shopgirl (which was made into a film) is another surprisingly emotional gem.

But a terrorism thriller about Muslim extremists and FBI investigations? Even with the understanding that "typical Steve Martin" territory extends much further than the casual fan might realize, this was not typical Steve Martin territory. Checking out the film's website, I found this explanation:

"Traitor began its journey to the big screen when Steve Martin presented an intriguing idea to producer David Hoberman while they were working together on the blockbuster comedy Bringing Down the House. Martin's "what if?" scenario immediately captured Hoberman's imagination with its provocative contemporary themes and surprising final twist."

The production notes go on to describe Nachmanoff and Don Cheadle doing a lot of reworking of Nachmanoff's script, which had been based on Martin's original concept, so I don't know how much of Martin's idea is in the finished product. (He's also credited as an executive producer.) But either way, as a huge fan of Martin's, it's always exciting to see him do something new. It's also nice to know that something positive came out of Bringing Down the House.

This is the perfect time for a road trip -- the sun is high in the sky, the weather is warm, and the roads are clear. But alas, the responsibilities of adulthood and busy scheduling don't always make the open road a viable option. Luckily, however, there's always the movies -- a million different cinematic road adventures to explore.

For this double feature, I'm giving you a little taste of the '90s and then a little taste of the '80s. One is a feature that helped start the careers of two notable actors, and spawned a terrible copy-cat film with Tom Green. The other made soft, warm pillows seem like more than just a wonderfully relaxing safe haven. Sit back and enjoy Overnight Delivery and Planes, Trains, and Automobiles.

Occasionally Hollywood cobbles together random members of the A-list to play family members on film, even if their genes obviously come from opposite ends of the earth. If the actors are good enough or if the chemistry is there, sometimes the combo can work, such as Ethan Hawke and Philip Seymour Hoffman as brothers in Before the Devil Knows You're Dead or Colin Farrell and Ewan McGregor in Cassandra's Dream. Other times, it stretches credibility, such as Adrien Brody, Owen Wilson and Jason Schwartzman in The Darjeeling Limited. My all-time favorite oddball casting is in Sidney Lumet's Family Business (1989), with Sean Connery, Dustin Hoffman and Matthew Broderick playing grandfather, father and son. (Huh?) At the same time, there are actor combos out there who just scream to be paired up in a family capacity. Remember Julia Roberts and Kyra Sedgwick in Something to Talk About? Well, neither do I, but that pairing was perfect. Here are a few others that could work:

1. Helen Hunt & Leelee Sobieski

They're so similar it's spooky, from their hair and foreheads, right down to the tonal quality of their voices. Anybody check the hospital records for mixed-up babies? (Helen is about 20 years older.) Not too long ago, both careers hit a peak: Helen won an Oscar while Leelee was working with Stanley Kubrick and playing Joan of Arc on TV. Now they're both in decline. For some reason, whenever Helen's name comes up, I hear "I HATE Helen Hunt!" And Leelee's last movie was for Uwe Boll. Now would be the perfect time for these two to team up in a mother-daughter drama. If they cooked up something along the lines of Terms of Endearment, with a good, solid writer and/or director, it could be interesting. Or better yet, how about something really strange and kooky with Spike Jonze or Harmony Korine? (Note: apparently the two once went head-to-head on "Celebrity Death Match.")

A confession: I have a downright unnatural willingness to laugh at a) people falling down, and b) people being hit by things. I think it's among the highest forms of humor. So it shouldn't surprise you to learn that I consider The Pink Panther -- the Peter Sellers version -- a national treasure. It may surprise you a bit more to learn that I thought the 2006 Steve Martin/Shawn Levy version was reasonably watchable. But, I mean, what did you expect from someone who adores a well-timed pratfall?

Sony has posted a teaser for the sequel here. The Pink Panther 2 is directed by Harald Zwart (Agent Cody Banks and the underrated One Night at McCool's), and has Steve Martin's Inspector Clouseau team up with a bunch of similarly bumbling international detectives to track down a thief of historical artifacts. In addition to the first film's Jean Reno and Emily Mortimer, it will also co-star Andy Garcia, Alfred Molina, Aishwarya Rai, and John Cleese (who's taking over for Kevin Kline). I don't know how I feel about Clouseau being placed among similar nincompoops -- part of the franchise's appeal is the way its protagonist is sort of an island of incompetence. But the teaser did get a chuckle out of me, if only for the look on Martin's face after pronouncing "Well then, I'll just go back home."

Did I mention that I also find bad French accents very funny?

UPDATE: We've been asked to take down the trailer as it hasn't been approved for distribution yet.

Note: You might want to kick up the speakers a bit here; this one comes in a tad low.

Above you will find the first trailer for the film Traitor, starring Don Cheadle, Guy Pearce and Jeff Daniels. The wild thing about this film is that Steve Martin (yes, THE Steve Martin) came up with the idea for Traitor, though he left scripting duties to writer-director Jeffrey Nachmanoff. Based on what we see above, Traitor seems like one of those "have fun figuring it out" types. Pearce plays a straight-edge FBI agent who heads an investigation on international conspiracy, where all clues lead back to former U.S. Special Operations office, Samir Horn (Cheadle). Thus begins what appears to be a dangerous cat and mouse game between the two -- with Daniels playing a veteran CIA contractor with his own agenda.

What I'm liking about this one is that Cheadle looks pretty rough, tough and ready to rumble -- and we don't get to see him much in roles where he can beat the living hell out of anyone within shouting distance. Go Don Cheadle! That guy always gives a tremendous performance, so no matter what I believe Traitor will be worth the watch just to see Cheadle in action. But let us know what you think.

Traitor hits theaters on August 29.

A comfortable and charming cinematic couple will reunite in two forthcoming comedies, but which will come first? At the end of March, Monika Bartyzel passed on the news that Steve Martin and Diane Keaton would re-team for the first time in more than a decade for the family comedy One Big Happy. Martin and Keaton were attached to the pitch from Party of Five creators Chris Keyser and Amy Lippman, which Paramount Pictures bought. Keyser and Lippman have other projects in various stages of development and no production timeline was mentioned.

Now, according to Variety, Paramount has bought another comedy pitch, this time from Steve Martin. Producer Robert Simonds presented Martin's idea for a comedy entitled From Zero to Sixty to all the major studios last week and Paramount was the "most aggresive in taking it off the table." Martin and Keaton would play a couple, but no other plot details emerged. Variety says production could start in the fall, but that's assuming a writer can be signed and the script completed very quickly. It may be that Paramount wants to fast track From Zero to Sixty because the script for One Big Happy will take a while to complete because of the writers' other projects.

Martin and Keaton starred together in Father of the Bride in 1991 and then followed that up with the sequel in 1995. Those films were very silly and forgettable, and I imagine these two new comedies will follow a similar path to box office success.

The first time I heard the term "Baby Mama" was probably on either Maury or Jerry Springer (don't laugh... you hear a lot of things as you're flipping over to PBS). It and its male equivalent, "Baby Daddy," essentially describes a person with whom you've had a child, but no other relationship currently exists. It used to be street slang, but in a movie world where pregnancy of all types seems to be the hot, go-to topic (Juno, Knocked Up), the whole "baby mama" thing was sure to come up at some point. I just never thought it would come from Tina Fey and Amy Poehler.

In Baby Mama, which opens the Tribeca Film Festival tonight and arrives nationwide on April 25, Fey plays Kate Holbrook, a successful vice president of a Whole Foods-esque organic supermarket chain. She's got the great job and the stunning Philadelphia apartment, but at 37, she longs for something more. You guessed it: Kate wants kids, and doesn't want to wait until she gets married to have them. One little problem: her chances of actually having a child are one in a million ("I just don't like your uterus," is what Kate's fertility doctor, played by The Daily Show's John Hodgman, tells her).

It has been over ten years since Diane Keaton and Steve Martin last starred in a film together -- Father of the Bride Part II. Now Variety reports that they're getting back into the family way for Paramount Pictures' comedy called One Big Happy. The pitch is the brainchild of Party of Five creators Chris Keyser and Amy Lippman, and while they are being tight-lipped about the premise, Variety sources say that it's "a family comedy about a couple and a family reconnecting amid various obstacles."

The question is: can this possible live up to hopes? A handful of years ago, I might have said yes, but in the wave of crappy films from Diane Keaton, it's hard not to worry that this will just be another one. Then again, maybe this will mark a turning point for the actress. Perhaps she can reinvigorate her career with the help of a little white-haired Martin. She has to have it in there somewhere, buried deep below Mad Money, Because I Said So, and some of her other recent films... To be fair, Martin has had some questionable flicks in there as well, but since I really enjoyed both Novocaine and Shopgirl, he gets some slack.

Now if they can get Martin Short for an even bigger Father of the Bride reunion, I'll definitely check it out.

It's kind of funny if you think about it, but Steve Martin really does have two entirely different careers. First, there is the goofy family friendly guy who stars in middling comedies like Bringing Down the House and Cheaper By the Dozen; and then there is the acerbic wit who writes abstract New Yorker pieces and stars in David Mamet films. Plus, occasionally he comes up with an idea for a movie of his own. RowThree.com is now hosting two new stills from the political thriller, Traitor. Martin will not be starring in this film, although he will serve as an executive producer. Originally Disney had lined up to produce the film back in 2002, but after a few staff changes at "mouse headquarters," the project was dropped.

Traitor stars Guy Pearce, Don Cheadle, and Jeff Daniels. Jeffrey Nachmanoff directed the film and the plot is is described as a "topical, politically relevant story dealing with international terrorism and U.S. traitors." Pearce plays FBI agent Roy Clayton; a straight arrow type who is drawn into a political conspiracy when everything points to a Special Operations officer (Cheadle). From there on it sounds like your usual espionage fare and, "obsessed with discovering the truth, Clayton tracks Horn across the globe as the elusive ex-soldier burrows deeper and deeper into a world of shadows and intrigue."

Nachmanoff isn't exactly a household name, but you might recognize him as the man who wrote The Day After Tomorrow (which isn't exactly good news, now is it?). But, I'll rely on the reputations of Pearce and Cheadle to guarantee me at least a decent popcorn movie if nothing else. Nachmanoff also wrote the script for Traitor before heading off to work on pre-production for Jerry Bruckheimer's video game flick, Prince of Persia. Traitor is still in post-production so a release date has not been set. Stay tuned to Cinematical for any updates that come our way.

Growing up, my two favorite comedians were Steve Martin and John Candy. My favorite filmmaker was John Hughes. And yet I was never allowed to see the collaboration of my three heroes -- Planes, Trains and Automobiles, because it was Rated "R" and my parents are mean. When I finally broke my father down and was permitted to watch it, I treasured every moment. And I still do. Maybe it's the years of anticipation that made the film so special to me, but it easily ranks among my very favorite comedies of all time.

John Hughes was in the midst of an amazing hot streak in 1987. He had written the screenplays for hits like Mr. Mom, National Lampoon's Vacation, Pretty in Pink, and Some Kind of Wonderful. His first four films as a writer/director had been Sixteen Candles, The Breakfast Club, Weird Science, and Ferris Bueller's Day Off, four of the most important films of my youth (and a lot of peoples' youths). Planes, Trains and Automobiles was a bit of a departure for Hughes -- an "adult" comedy, with nary a teenager in sight. Thankfully, Hughes knew the complicated world of adult relationships and feelings just as well as he did that of teens.

Martin plays Neal Page, an uptight advertising man who is trying to get from New York to Chicago in time for Thanksgiving. John Candy plays Del Griffith, a slobby shower curtain ring salesman who is headed the same direction as Neal. For better or worse, they wind up taking the trip together. Tale as old as time. But beautiful writing, pitch-perfect performances, and a surprisingly powerful undercurrent of emotion make Planes, Trains and Automobiles the buddy comedy by which all others must be judged.
