1) To skeptics about playing cards: Have you never gotten a paper cut? A paper cut is the result of pulling a narrow, not-at-all-stiff object along a pliant-incredibly-the-opposite-of-stiff surface, the result being that the slightly more resilient former slices through the latter. A playing card has speed and a very narrow profile in its favor. It also has a remarkable resiliency and strength. Yes, you can bend a playing card. Yes you can tear it. Have you ever tried grabbing it at either end and pulling it apart? It's made of woven fibers and you'll find it quite strong. It's a single unit and, with both forward speed and rotation in its favor, it can tear shit apart. The difficult part of slicing something with a playing card isn't the slicing, it's making it move a long distance at speed, and that's been captured on film. I speak as someone who has never bought and will never buy an x-man comic book.
2) Ryan Reynolds: I honestly believe that he's a remarkably capable actor. I saw only about five minutes of Amityville horror and he scared the crap out of me with the axe and all. Hell, most of what he's done is comedy; think how hard it is to say what he's said with a straight face. And then couple that with his role in Blade: Trinity*, the fact is that he can walk into a role and own it, no matter how good or absurd it may be, and then give it his own personal spin. The dude makes it look easy. Plus, he's gorgeous. That's not unimportant. Hell, I think it's the only reason for the success of Tom Cruise.
* Personally, I think the Blade movies are utter shit and Wesley Snipes is an execrable actor, but that doesn't change my impression of the various actors involved in the project.
Kris Kristofferson: old guy, should stick to country music.
Ron Pearlman: should stick to fallout intros.
The Guy from Boondock Saints: Should stick to Boondock Saints.
The Guy who played "the dracula": should stick to underwear modelling or whatever.
