WARNING: Possible Spoilers Ahead!
"There is a cameo by John Romita Jr., the other author of the book, which nobody has spotted yet because Johnny has his back to you in the cameo," Millar told MTV News about the comic book artist's role on screen as a bartender. "Yeah just for a fraction second you see him."
"I had a little cameo as well, where I was playing an alcoholic, a Scottish alcoholic. And that got cut from final of the movie, hopefully it’ll end up in the extended version that Matthew’s working on," the writer revealed. "I was hoping to be something cool like a Special Forces guy or something. And they said, 'No no, you’d be great as a Scottish Alcoholic' and I was like, 'okay.'"
Millar also said that fans should keep an eye out for the appearence of some of his past comic book work and let's slip some info about Red Mist's new name in the sequel at the same time, "In the final scene where you see Chris Mintz-Plasse going from Red Mist to the character of The Mother [frick]er — the bad guy he becomes at the very end of the movie — you see a copy of 'The Ultimates' lying on the desk and 'Ultimate X-Men.'"
"I also threw in a lot of stuff from my friends as well. Like Brian K. Vaughan, I think he is a great writer, so I made sure one of the guys was was reading a copy of 'Runaways' in the comic shop."
"So even if these guys never get movies made, at least they were in a movie!"
