Bobby Moynihan, 'Monsters University' Star, On Working With Pixar & Chris Christie

Billy Crystal isn't the only "Saturday Night Live" favorite to lend his voice to "Monsters University": former cast member Bill Hader and current star Bobby Moynihan provide their vocal talents to the prequel to "Monsters Inc.," while 12-time "SNL" host John Goodman reprises his part from the first film as well.

"Me, Billy Crystal and John Goodman hang out non-stop and all we do is silly voices," Moynihan joked during a recent appearance on HuffPost Live. "We hang out in a little closet and do voices together."

They don't, of course; Moynihan actually recorded his part, that of snotty fraternity brother Chet, alone in a studio. Not that it was difficult. "It's no weirder than dressing up like a lady on 'SNL,'" Moynihan offered during appearance. The New York native is famous for his impersonations on the late-night sketch comedy series, including Snooki and New Jersey governor Chris Christie.

"He's the nicest guy in the world," Moynihan said of Christie. "I'm not very big on politics. I'm a comedian and not that smart. I don't have the mind capacity for it. But when I listen to him talk, I just feel like I trust that guy."

As for what Christie thinks of Moynihan's impression, the 36-year-old said he approved. "He was super nice. He sent a letter to my mom and dad. He's a class act,"

Watch the full interview with Moynihan above for more on "Monster University," "SNL" and his career. "Monsters University" is out in theaters on June 21.
