If I HAD to pick a film I would say "The Matrix" but I'm not sure it should be called influential.

I'm not basing my questions off what we've seen though. If you check out IMDB for the flick you see Ryan Reynolds down for Deadpool and then Scott Adkins down for Weapon XI. I'm just questioning why not if they were going to have Deadpool "mutate" into this Weapon XI character not just use Ryan Reynolds for that as opposed to getting a completely different actor. I'm not saying it's not possible, just wondering the thought process behind doing that is all.

And of course this is still just all speculation at this point. The new trailer makes me feel a little better about the flick cause I wasn't sure about it when I kept reading rumors about Fox execs coming onto the set and meddling with things. I'm a little peeved about seeing Cyclops though. We already have so many mutants in this flick why involve ANY of the X-Men? Oh well, the countdown is on for me.
