Seth RogenSeth Rogen has said he feels he needs to go full frontal to be able to keep up with his comedic contemporaries.

The Knocked Up star shows off his bum in Kevin Smith’s new film Zack and Miri Make a Porno but he’s revealed he thinks that’s passé these days - it’s all about the penis now.

He explained recently: “Last year a movie came out, Forgetting Sarah Marshall, with Jason Segel - who I’m actually friends with.

“He shows his frontierre on that, but as soon as I saw it, it was like when the first guy dunked in basketball - all the other guys are like, ‘Now I’m going to have to dunk to stay in the game’.

“As soon as I saw his penis, I was like, ‘Now I’ve got to show mine to stay in the comedy game.’”
