Chemistry -- you can be the best filmmaker, writer or actor, but nothing makes up for a lack of that intangible connection between two people. This is probably why so many actors can't keep up long relationships -- they continually get paired up with people they have great chemistry with and are weakened by temptation over and over until they can't help but break the ties that bind and go libidinously nuts. Oh, the devilish temptation! But on the flip-side, there are pairings that are just plain crappy -- painfully free of that interest and attraction that comes from the eyes. The CBC has reported that British cinema advertisers Pearl and Dean recently conducted a survey asking 3,000 movie-goers which duos have the worst on-screen chemistry, and came up with a list of the 10 worst offenders.

The top spots are no big surprise, really -- the 5th went to Catherine Zeta Jones and Sean Connery in Entrapment, the 4th to Madonna and Adriano Giannini in Swept Away, Keira Knightley and Orlando Bloom got the third spot with the Pirates of the Caribbean trilogy, the runners up were the rockin' Bennifer pair for Gigli and the top spot went to Natalie Portman and Hayden Christensen with Episode II: Attack of the Clones. I'd say they're pretty spot on, although my top offender are the two that hold that third spot, and I'm glad I'm not the only one that thinks so. Granted, Johnny Depp can whip up some chemistry with almost anyone, which makes it hard to compete, but man, I hated Knightley and Bloom together. This also made many parts of the final film truly annoying, if you get my drift. Also, you've got to question your real-life couple choices when you can't cook up chemistry at work, with your significant other.

Finishing the list, there's Hugh Grant and Andie MacDowell in the 6-spot with Four Weddings and a Funeral, Ben Affleck appeared again at 7 with Kate Beckinsale for Pearl Harbor, Tom Cruise and Nicole Kidman got 8 with Eyes Wide Shut, Heath Ledger and Jake Gyllenhaal followed with Brokeback Mountain and Titanic got the final, 10th spot, with stars Kate Winslet and Leonardo DiCaprio. Who would you pick?

Although he already staged one triumphant return after shelling out that abysmal love letter to his wife (the only thing swept away in, well, Swept Away was the career of its director), Guy Ritchie is attempting to make another comeback; this time, he's going to stick to what made him famous in the first place. The Hollywood Reporter tells us that Ritchie will direct RocknRolla for Joel Silver's Dark Castle Entertainment. And, contrary to what you might think based on that title, it will not be some '70s-style rollerskating-themed musical comedy. Oh no, this pic is said to be in the same vein as Lock, Stock and Two Smoking Barrels and Snatch. So, basically, they'll be a bunch of British gangsters fighting over a missing bag of drugs while singing show tunes on roller skates. I dig it!

Ritchie, who also penned the script, plans to begin shooting the film this summer. With casting currently underway, me wonders whether Ritchie is still hot enough to land some big-name talent. Right off the bat, I think it's pretty safe to assume Jason Statham will make an appearance, as he's starred in three of Ritchie's four films. Apart from him, this puppy is way up in the air. If he's reaching into a hot British talent pool, perhaps we'll see Daniel Craig or Simon Pegg show up. Or how about Clive Owen? The dude starred in that Ritchie-directed BMW short film; maybe he'll be down for a little smash and grab action? However, the fact that Dark Castle Entertainment is producing doesn't exactly sit right with me. Should I even go near the last seven films they churned out? Let's see, amongst that lot we have gems like Return to House on Haunted Hill, The Reaping, House of Wax and Ghost Ship. Now I know why it's called Dark Castle -- that's the place Joel Silver dumps all the crappy films no one wants to go near.
