5. A Writer Who Can’t Draw Feet
Deadpool creator Rob Liefeld got treated to a brief cameo in the first movie (Wade greets him by name at Weasel’s bar), but the sequel opts for a funny dig at the writer instead. Deadpool 2 sees the introduction of Domino (played wonderfully by Zazie Beetz), a mutant with the ability to alter probability in her favor.
While the film has a lot of fun with showing Domino’s insanely good luck put to practical use, it is a bit of a silly power. Deadpool is incredulous when he first learns about Domino’s abilities and says that it’s an idea so dumb, it could only be thought up by a writer who “can’t draw feet.” Seeing as how Liefeld (who also created Domino) has a reputation among comic fans for not being able to draw feet well, he’s the one Deadpool is referring to here.

4. Say Anything
Probably a bit obvious, but when Deadpool arrives at the X-Mansion to try and win back Colossus, he plays a song from a boombox app on his phone and holds it above his head. This is a clear reference to the iconic boombox scene from the 1989 romantic comedy Say Anything… starring John Cusack and Ione Skye.

3. Juggernaut Voice
The reveal of Juggernaut as the main villain in Deadpool 2 is one of the film’s biggest (literally) surprises and the fact that his inclusion was kept under wraps right up until release might be the most impressive feat of all. Fortunately, this new version of the character is much more faithful to the comic book version than Vinnie Jones’ portrayal in the abysmal X-Men: The Last Stand, as he’s much more of a terrifying physical threat. This Juggernaut is a pure CGI creation and this fact is rather cheekily acknowledged in the credits, where he’s listed as being played by himself. However, it has since been confirmed by 20th Century Fox that Juggernaut is in fact voiced by none other than Ryan Reynolds.
Additionally, Deadpool 2 also references Juggernaut, a.k.a. Cain Marko having a brother in a wheel chair who was able to read his mind before he put on his helmet. It’s not hard to connect the dots here and realize that his brother is Charles Xavier, which is comic book canon.
