Ryan Reynolds as Wade Wilson / Deadpool

Ryan joins Burt in the Reynolds Hall of Fame, wherever that may be. He’s always been unfairly handsome, he’s never been funnier. Nor richer, as huge hit Deadpool is for him what Iron Man became for Downey.

The Character per Wikipedia

A mercenary who is subjected to an experimental regenerative mutation to cure his cancer, which gives him accelerated healing superpowers, but severely scars his body. Reynolds called this version of Deadpool more “authentic” and closer to the comic version than his X-Men Origins: Wolverine version, saying that this Deadpool “takes nothing seriously.”

Ed Skrein as Francis Freeman / Ajax

An artificially-mutated member of Weapon X, the program that creates Deadpool. Ajax is a weapons expert, with enhanced strength and an inability to feel pain. According to Tim Miller, Skrein did ‘80%’ of his own stunts, with stunt doubles only used for rigged stunts.

Stan Lee – Strip Club MC

Yes, there is a post-credits scene. Yes it’s worth staying for. This is a Marvel film, dammit.

Rated R for a reason, Deadpool makes sport of decency. It’s gleefully indecent.

It also introduces a lead character who’s more than bisexual, he’s pansexual. Yeah, another term to learn. Blamed on the deathly toxins that went through his mind, its affect is to turn him into a coquettish rogue.
