The opening credits are placeholders for what was in the script. "As written by Deadpool"; "Some douchebag's film, Starring God's perfect idiot (referring to Ryan. Accompanied by an Easter Egg of Ryan's People Magazine cover as Sexiest Man Alive); "A hot chick"; "A British villain"; "The comic relief"; "A moody teen"; "A CGI character"; "A gratuitous cameo"; "Produced by asshats"; "Written by the real heroes here"; "Directed by an overpaid tool". There are Easter Eggs as well: The card in the wallet of Ryan in a green suit, the thug with the lighter was originally a filmed joke in reference to Colin Farrell in Daredevil (2003), "Rob L." on the coffee cup is Rob Liefeld, the little sex key-chain, the Orange Number 5 card, and the Hello Kitty.
The scene after the credits shows Deadpool in a bathrobe, making fun of you, the viewer, for sticking around for so long. It is an homage to the post-credit scene in Ferris Bueller's Day Off (1986). He also talks about the sequel, and says it will feature Cable. Then he makes a few jokes about the casting, and pokes at other movies that usually tease future movies in these scenes. The final "chika-chikaa" he does refers to the song "Oh, Yeah", by Yello, which is featured in that movie.
A cartoon version of Deadpool runs wild around the credits.
The main credits, including the title, aren't revealed until the end of the movie.
The opening credits appear in a zoom out of a frozen moment from Deadpool's highway fight. The zoom shot contains a variety of jokes and Easter eggs, and ends with a children's drawing of the title character.
