The Reno 911 actor, who plays creepy Carl Halabi in the new comedy, told BlackBook that while he has only a small role in Bad Teacher, he is happy to be a character actor as it allows him to take on more outlandish parts.
"My total work [on Bad Teacher] was five days. As you noticed, I was the supporting character," Lennon explained. "I'm probably the highlight of the film. I feel like I'm putting words in your mouth when I say it, but I'm probably the highlight of the movie."
"I'm not on for a long f***ing time, and even then I don't do that much. That's the art of my role in films. Don't be on that much, and then do hardly anything... But that's what happens a lot of the times when you are a character actor. You come in out of nowhere, see a whole established cast and crew... and take your pants off, and kinda d**k around."
Lennon also had positive things to say about Bad Teacher star Cameron Diaz, adding: "We got along pretty well. I don't know if it's fake - I don't think it is, because she seems like a pretty sincere person. But she's one of those people you like right away.
"If you make her crack up it kind of makes you feel like you won."
