Ryan Reynolds -- Deadpool Outfit Is Dead On ... And Tight On the Junk

SPOILER ALERT: Ryan Reynolds looks badass as Deadpool and is set to make a ton of comic book nerds very excited.

Reynolds was on the Vancouver set of the upcoming Marvel movie wearing Deadpool's full regalia ... and looking spot on as the anti-hero. Just a guess based on the pics, but Ryan might want 'em to let out the inseam a little -- especially if the movie spawns sequels.

The movie is set for a 2016 release and will also feature Ed Skrein, Silicon Valley's TJ Miller and Gina Carano.

If you haven't seen the footage that was responsible for the whole project getting greenlit ... drop your swords and treat yourself right now.
