Katharine McPhee recently talked to MTV about her first starring movie role in I Know What Boys Like.

“This is very different,” said McPhee, looking around a set that included Anna Faris, Colin Hanks, Emma Stone and Rumer Willis. “I can see how people would get freaked out on sets, because there’s so many people behind the camera and you get only a few chances - depending on who the director is - to do what you have to do.”

Of course, being on the smash show that American Idol is helped McPhee adjust to the craziness and attention.

“I’ve felt really comfortable, actually,” she said.“Coming from a show that millions of people watch, it’s a lot less scary. So, I’ve had a blast. The whole [movie] experience, this whole environment, is like a family. You get to know all the faces, all the grips, all the stagehands and stuff like that.”
