If and when they make a movie centered around Onslaught, they need to make it a crossover movie, otherwise it just wouldn't feel right. Spider-Man, Iron Man, Fantastic 4, the whole nine yards. Recasting wouldn't be a problem, but with the characters already being played by actors in other movies, they should stick with them to give it a sense of continuity.
Never have I been more interested in an American comic book series. I'm gonna have to check out this Deadpool. (Recalls someone on the forum always having signatures from it, forget who.)
I though it was Freeman-12, but if it was, he has since changed his avatar and sig. Dythim on K-F has a Deadpool Avvie and signature, though.
Deadpool cracks me up for the simple fact that he seems to be the only marvel character to consistently break the fourth wall. That and he's a looney. I've got a bit more Pics I'll PM you later.
