Prehistoric caveman or action hero? As our own Jenni Miller recently posted, David Fincher is in talks to direct The Social Network (AKA "The Facebook Movie"). Naturally enough, speculation has begun on who could play Facebook founder Mark Zuckerberg. CNET News was told by "an entertainment industry source" that Michael Cera and Shia LaBeouf are among the top choices.

But they're on the top of the list for just about any movie featuring a 20-something lead, aren't they? Would either one be suited for the role? The red hot LaBeouf would seem the more logical choice ... except that he's already set for Money Never Sleeps (AKA Wall Street 2) and has The Associate (based on John Grisham's latest best seller) in development. One's about the financial industry, the other takes place in the legal system; a third movie set in the business world in the next couple of years might prematurely age his star.

Cera might be the better choice. Even though Year One flopped, he was the second banana and doesn't seem to have suffered from the box office fallout. The upcoming Youth in Revolt and Scott Pilgrim vs. the World could cement his appeal, setting him up for a dramatic turn with a very talented director. I'm curious to see if he can expand beyond his usual shtick; at the same time, his comic chops could come in handy, depending on Aaron Sorkin's script.

Would you rather see Michael Cera or Shia LaBeouf as Facebook founder Mark Zuckerberg? If not them, then who?

If you don't know your Megatron from your Optimus Prime, join the club! Most giant robots look all the same to me, and the first Transformers movie felt like a comedown for Michael Bay after the gleeful insanity of Bad Boys II. Still, I've gotten a kick out ot reading a few of the reviews, like the one penned by our own Todd Gilchrist, as well as the harsh critical takedowns by Roger Ebert and Manohla Dargis. And now I'm wondering how Transformers: Revenge of the Fallen will perform at the box office. Can it possibly recoup its huge production and marketing budget? How big is big?

The movie is off to a running start, earning an estimated $16 million from midnight screenings last night, according to Variety. That's less than The Dark Knight's $18.5 million last year, but Variety notes the Batman flick "had the advantage of opening on a Friday" and that Transformers 2 had "the best midnight run ever for a movie opening on a Wednesday." Transformers made $8.8 million on its opening night (Tuesday at 12:01 a.m.) in 2007 and went on to earn $146.6 million in its first six full days of screenings, including the July 4 holiday, per Box Office Mojo.

The record to beat for the first five days of release is $203.7 million, set by The Dark Knight. Can Transformers: Revenge of the Fallen get anywhere near that record? Take our poll and let us know: How much will it make in its opening five-day weekend?

After resisting overtures for a decade, a best-selling author received an offer he couldn't refuse. John Grisham has finally allowed his 1999 novel The Testament to be optioned, according to Variety. Grisham will have "the right to provide creative input, which he didn't always have in the past -- one of the factors that pushed him away from Hollywood until about three years ago, when his fans prodded him to end his self-imposed movie moratorium."

The Testament revolves around a self-made billionaire who leaves his entire fortune to his illegitimate daughter, a young woman who lives and works "with a primitive tribe of Indians in the deepest jungles of Brazil." An attorney who's seen better days helps her battle the billionaire's relatives for the fortune. Producer Mark Johnson says: "It had the best of the courthouse stuff that John writes so well, plus this exotic adventure in deepest Brazil."

It's been six years since Runaway Jury hit the screens, so is the time right for more big-screen Grisham? I jumped off the Grisham bandwagon after The King of Torts, which had a smug, off-putting, moralistic tone; his formula -- idealistic young hero / heroine fights the corrupt system -- felt stale and predictable. If nothing else, Grisham's books offer the comfort of familiarity. Legal thrillers, the more formulaic the better, are a Hollywood staple, and usually attract a dependable audience. Shia LaBeouf is attached to The Associate, his latest best-seller, and others are in development. Will Grisham's creative input on The Testament result in a better movie?

I spoke too soon. We all did. After the heartening news that Shia LaBeouf wasn't interested in being the last man on earth (to which every other guy on the planet yelled "Fool!!"), he's hastily amended his brush-off to Collider.

While he still feels the part of Yorick is too "Sam Witwicky" and stresses that he wants to do something that's "foreign," he's still very interested in Y: The Last Man. He just wants to wait a few years, and he'll have the time to get the Witwicky out of his system.

"I love Y! Y is my favorite comic book ... Brian K. Vaughn, Neil Gaiman, the guys who write the Criminal series, these are all my favorite, this is my favorite stuff to read. It's the stuff that I love. Y: The Last Man is my favorite comic book. It's also DJ Caruso's favorite comic book. We DO want to make it ... Absolutely, man! In fact, that's what's going on right now. Vaughn and Ellsworth and DJ are writing the script now. The script is not ready to be shot. DJ is making a different movie right now. He's making Jack and the Beanstalk. There's just other things going on with DJ and I wouldn't want to make the movie with anybody else because he loves it like I do. But I don't think Vaughn is trying to give it to anybody else. I think that it is something that's very realistic, it's just not in the pipe for the next year."

Well, I'm pleased that he's a fan of the series and who knows? Maybe a few years will see me warm up to him, and be delighted that he was the first pick for the last man.

As a high-school graduation present to myself in 1993, I stayed up all night watching the original Star Wars trilogy on video. When the Extended Edition of The Return of the King arrived on DVD, I camped out on my couch and sat through all three Lord of the Rings films in their longest versions, one after the other. And for two separate retrospective assignments in anticipation of their recent big-screen rebirths, I endured all ten Star Trek movies and all eleven Friday the 13ths. But I can honestly say that as a film critic and lifelong cinephile, Transformers: Revenge of the Fallen may be the most movie I have ever experienced.

Michael Bay, condensing the cumulative total of the spectacle from all of his seven previous films into one unwieldy, gargantuan opus, has exceeded even the possibilities of sequel-driven "moreness," combining his own muscular, high-gloss sensibility with the conventions of blockbusters past, present, and probably future to create a monolithic action masterpiece that feels destined to be the biggest movie of all time.

Mere days after Shia LaBeouf gleefully announced that Steven Spielberg had "cracked" the story for Indiana Jones 5 comes another confirmation that it'll rear its ugly head. Empire Online caught up with Indiana Jones' longtime producer, Frank Marshall, who didn't go so far as to green-light it, but revealed that they'll start hashing out ideas before too long.

"It's really about the script," said Marshall. "Once we see that, we'll see. We're not going to wait another 20 years. We'd all love to make another one. I'm anxious to hear the idea!" But he quickly added that he really didn't know what Spielberg was cooking. "Until there's a script, nothing's definite. I haven't heard the idea." (He should ask LaBeouf. I bet he knows.) Marshall also confirmed that Lucas, Spielberg, and Ford were equally eager to return for a fifth outing. "Yeah. We had a great time making the last one and, as Harrison said, we need to make this one soon. We're not getting any younger."

While talk is talk, and plans vanish, bear in mind that they were already chattering about a fifth outing before Kingdom of the Crystal Skull hit theaters, and were still dreaming of it after, despite the negative reviews and fan backlash. I have no doubt it'll happen regardless of what the fans say or think. When it does, that shrieking sound you hear? That'll be the death cry of my fangirl soul ... and I'm sure it won't be the only lament visited upon the heavens.

Ah, the sequel no one is clamoring for has reared its head again. To be fair, some people enjoyed Indiana Jones and the Kingdom of the Crystal Skull, and with worldwide gross receipts totaling nearly $800 million, the only question that remained was when Steven Spielberg, George Lucas, and Harrison Ford would be ready to give it another go. (Our own poll last year suggested that it was time to retire the franchise.) Reportedly, Lucas favored the idea of continuing with old Indiana Jones as the lead character rather than handing things over to young Mutt Williams, played by Shia LaBeouf. Research was being conducted to find an artifact that the movie could be based on.

In the UK to promote Transformers: Revenge of the Fallen, LaBeouf talked to the BBC and revealed that he had spoken recently with Spielberg about another Indiana Jones movie: "Steven just said he cracked a story on it before I left. I think they're gearing that up." Spielberg is busy filming The Adventures of Tintin: Secret of the Unicorn, so maybe he talked with Lucas between shots: "Hi, George, it's Steven. What if Indy searches for a shabti?" "Steven, what's a shabti?" "You know, George, the Sorcerer's Apprentice, the inspiration for that segment with Mickey Mouse in Fantasia?" "Of course, Steven, who do you think you're talking to?" "Well, George, the shabti was a figurine that was buried with the dead and performed hard labor for the deceased in the afterlife." "Ooh, I know, Mutt could try to get to it first, so he would never have to do manual labor for Indy any more!" "George, I think we've cracked it."

We'll wait to see if an official confirmation seeps out. Are you holding your breath for Indy 5?

What did you like the most about Transformers? Was it Megan Fox bending over an automobile hood? Shia LaBeouf learning to be a man behind the wheel of a yellow Chevy Camaro? Huge mechanical beasts suddenly emerging from the least likely hiding places? The military unit that found itself in the middle of an interstellar war in the middle of the desert? If it's the latter, you're in luck. Though the trailers and clips released for Transformers: Revenge of the Fallen have focused mainly on the Fox and the 'Bots so far, the military men finally get their due in the latest clip. (Note: the image above is not from the clip, but gives off a similar vibe.)

Moviefone has a short, tantalizing teaser clip that focuses on a unit led by Josh Duhamel, which appears to have gone international (check the arm patches). It's nighttime and they're flying in on helicopters to deal with the latest "enemy contact." Tyrese Gibson gets to mutter my favorite two words so far: "Thermal ripple." Despite my huge reservations about the first film, it's hard to resist whirling helicopters, bombastic martial music, a cool nighttime setting, and giant robot action, especially when it's all packed into a clip that's barely more than a minute long. Transformers: Revenge of the Fallen opens everywhere on June 24.

After the jump: Watch the clip!

Now that we're only a couple of weeks away from the debut of Transformers: Revenge of the Fallen, some new behind the scenes videos are beginning to pop up online. I love this stuff -- it really gives you a great look at what went on behind the cameras, and how the film you watch on the big screen actually came together. Brilliant stuff, I tell ya. Well, in this latest video from Landline TV, they reveal that actress Megan Fox (who plays Shia LaBeouf's love interest in both Transformers movies) is actually all CGI. See, and I knew girls weren't that beautiful in real life! TOLDJA!

Go behind the scenes with producers as they reveal how Megan Fox was created, and what it was like to shoot the film pretending like this unbelievably gorgeous girl was there when she really wasn't. Also, watch as the filmmakers announce for the first time ever a new version of Transformers: Revenge of the Fallen where you put a pair of glasses on and everything turns to Megan Fox. Quite amazing what they're doing with special effects these days -- now I just need to find out whether they'll be auctioning off one of the seven Megan Fox animatronics created specifically for the sequel because, well, I'm definitely going to want one of those for my ... um ... collection.

Watch the video after the jump.
