I hadn't seen any images or Wallpapers of Deadpool. So I decided to find some myself and I did. I like the idea of them not going full costume for Deadpool as far as I know this will be what he's wearing, a red shirt, brown pants, black army boots, two swords mounted on his back and two side gun holsters. Personally I like his outfit in the comics but it just wouldn't look right in a movie so I'm ok with his outfit in the movie.
Ryan Reynolds as Deadpool is also a good choice I think he's a very funny guy. But here what I don't like the whole weapon XI thing, from what I've heard this is Deadpool turned into a mute mutant with all of the weapon X teams powers put together.
I'm crossing my fingers that it's just a clone of Deadpool and not Deadpool himself or if at the end of the movie he turns back to normal. I guess we'll have to wait for the movie to be released to find out.
