"Kick-Ass 2" stars Donald Faison and Christopher Mintz-Plass stopped by the CBR Yacht during Comic-Con International 2013 to discuss everything about the upcoming sequel -- including the uncomfortable nature of wearing superhero and super villain costumes, working with comedy legend Jim Carrey and more. Plus, watch them jam out with CBR cowbells to open and close the interview!

On wearing super-hero costumes during shooting: "It was miserable to wear," Mintz-Plasse said of The Mother Fucker's outfit. "I had to drink water -- I literally don't think I peed once, I think I sweated all the liquid out. It was crazy, but it looks amazing, it looks fantastic and I think people are going to like it."

"The worst thing about these costumes is putting them on and then having to take them off to go poop," Faison added. "It's the worst, because it's really an ordeal."

On Faison's joining the cast of actors from the original "Kick-Ass": "In all honesty, we've all known each other outside of doing 'Kick-Ass,'" Faison said. "I met Chris before, and it's easy to work with people who you know. It's also easy to work with people who you admire or who you think are really good."

"It's great to shoot a movie not where you live," Mintz-Plasse offered. "Because you're almost forced to hang out with each other. Like, when you were filming in London, you and Clark [Duke] went out a bunch and kind of bonded. We went out, too."

"It's like being Billy Dee Williams in 'Empire Strikes Back' and coming in to being Lando Calrissian," Faison said.

On working with Jim Carrey: "I only worked a day with him, but his movies in the '90s were reasons I got into acting and comedy," Mintz-Plasse said. "For a kid, when I was 9 years old, 'Dumb and Dumber' was the greatest thing ever. To have one day with him was incredible. He would do takes that were 15 minutes long, and Jeff [Wadlow] would come in and be like, 'We got it,' and Jim would say, 'No, I want another one.' I've never really been that guy, but it inspired me that if I don't feel I got it, I can tell the director, 'I want more.'"

On Carrey's recent comments distancing himself from the film: "He's allowed to his opinion, you know what I mean?" Faison said.

"Yeah, it is what it is," Mintz-Plasse added. "I wish he was here -- he's so good in the movie and he's such a funny guy to have on the panel and to promote. He would have killed with, but it is what it is. The man's got his opinions."

"He's really good in the movie, he's so good in it," Faison said. "He came with all that stuff himself -- him and his makeup guy, they put the prosthetics on and he came to set!"
