Jason Segel cut his "gratuitous" fully nude scene from The Five-Year Engagement.

The actor is no stranger to baring his manhood on camera - having done so in 2007's Forgetting Sarah Marshall - but even though it was his idea to do it again for his latest film, he ultimately decided it was too much.

"I thought of it at the time as a homage to Sarah Marshall, but then when we saw it, it just seemed gratuitous... There's no need for it. People already know what it looks like, and we also couldn't find a lens that was wide enough," he joked to The Huffington Post.

The film's co-writer and director, Nicholas Stoller - who also worked on Forgetting Sarah Marshall - joined in joking about his friend's manhood: "His penis was getting a bit of an ego. And you know what? It hasn't changed much since Sarah Marshall. I'll be honest. It's basically the same."

Nicholas also promised The Five-Year Engagement features plenty of shots of Jason's bottom, and praised his bravado in being prepared to show himself off on camera: "He's never afraid to show flaws or a certain ugliness in the characters that he plays. He's always been like that, since he was a teenager and we started working for him. When we first met him, we were like, 'Yeah, this guy is probably going to become famous, but in a weird way.' He has a weirdness that is more relatable."
