What's with the "Ryan Reynolds" hype??
C'mon. Different people should always play different comicbook characters.
One should not do more that one character especially if it's the same comic book company especially if said characters have been allies, especially if said movies are coming out at around the same time.
For example you got Ryan starring in "The Green Lantern" movie, as Green Lantern, in the same year, he's gonna be deadpool in the new "Deadpool" movie. Then he'll star as The Flash in the upcoming "Flash" movie. Talk about overexposure. How can you be 2 DC characters, teamates, and not have a "wtf?" factor, essentially ruining the experience.,
I dunno, maybe it's just me but the movie's would seem just odd or something you couldn't get into cause you'll always picture this actor as those other superhero characters.
