I think the voice actor in this one is the guy who did DP in the hulk vs. movies and in MvC3.
On the note of RR and the DP movie, he came out and said:
"I love Deadpool and there is a script that’s in development. But it’s so, so far into the R-rated zone… it’s a nearly NC-17 world and I just don’t know if the studio would ever risk their reputation doing it. We’ve been developing it and we would never wanna do it unless you could it that R-rated way, so…"
"[The Deadpool script has] got a similar tone [to Zombieland], almost. They wrote it and they developed it as well and, you know, it’s sitting there. You could do it for a pittance compared to the modern sort of epic scale superhero movies, but it’s about a guy who knows he’s in a movie and knows he’s in a comic book who is deeply mentally disturbed and hyper violent. And that’s tough to get by a studio."
