Zac Efron discusses Leslie Mann and Matthew Perry in a recent interview:
"After five minutes of talking with Leslie, I had a crush on her. She so natural and funny and sweet. She's very interesting. That was one thing about working with her. Leslie is unlike any actress I've worked with before.
"She's very honest and real and in the moment. You have to be ready for what she's going to throw at you and that's very intriguing.
"It was funny putting myself in the character of a 37-year-old dad because there was so little experience that I could draw from. It must have been frustrating for the director.
"It would be so easy for him to see where a father would come from in a situation and he would try to communicate that to me. Inevitably he would realise there were so few ways I could relate to a 37-year-old guy.
"It was fun for me because it was a challenge, it was different. I wasn't playing a high school kid.
"Until now, a lot of stuff I had done I had lived. First love, been there, done that. High school, putting on plays, I've done that, I've experienced it. Whereas in this movie, I'm doing things that someone twice my age has barely done yet."
Working with Matthew Perry has been one of the highlights of Zac's whirlwind career. "I definitely watched Friends," he said.
"I definitely knew who Matthew was. It wasn't like I had to discover this guy.
"He's a comedy icon and I was very excited when he signed on to do the movie.
"I could imagine what he could have been like as a teenager. And that was very funny.
"He was probably even more quick witted and he probably had a really sharp tongue and he was smart and sarcastic. So it was fun to try to imagine that and figure him out."
the ripping off of pants... lol.
