Despite appearing in three previous "X-Men" films in limited capacities, "Deadpool" marks the first major role the Russian X-Man in film. As a completely CG character, though, it took more than just one actor and some computer effects to make the metal mutant shine on screen. Colossus was played by Daniel Cudmore in 2003's "X2," 2006's "X-Men: The Last Stand" and 2014's "X-Men: Days of Future Past"; this time around, it took over half a dozen performers and crew members to bring Colossus to life.
"Deadpool" motion capture performer TJ Storm provided a list of names of those involved with creating Colossus, posting the group members' names to Facebook.
Andre Tricoteux performed Colossus on set wearing a gray mocap suit. He was originally slated to voice the character but it was announced late in production that that job would go to Stefan Kapicic. Greg LaSalle, who provided facial acting for the X-Man, also spoke about the hardest part of his performance -- the puking.
"Trying to vomit when you're acting is, physically, an incredibly physically draining thing," said LaSalle in an interview with ComicBook.com. "Unfortunately, since motion capture, like I was saying, you just do the takes, loop and loop and loop. By the time you do 10 vomit sequences, and there aren't that many in the film, but you're doing it over and over again to try and modify that. I actually was almost really vomiting on the cameras, because you're whole body has to get into it to make it look real. You know, you can't pretend to vomit, it'll look like you're pretending to vomit. So, at one point [director Tim Miller] was like, 'Dude, you got to stop, because you're going to pass out and you're going to throw up on the cameras.' That was incredibly physically challenging."
