Why Casper?
Okay, so I'm admittedly a sucker for a pretty face. And let's face it, his face is darn pretty (so's the rest of him).  Anyhoo, I'm not a big 90210 fan, and I don't really understand the appeal of Casper.  Granted, he's not the greatest actor ever, but at least you can look at the pictures and be happy.  So there, Casper is in here to serve as eye-candy for all you people out there who secretly tape Melrose and would never admit that to your friends ("Oooh, I love ER! Such a great show, great acting, blah blah blah....damn, where's that Melrose tape?...")  Also, Starship Troopers was actually a fun movie, once I accepted the fact that it wasn't exactly an Oscar-contender.  Casper looks spiffy in the body armor, packing the big guns. :)
