Jason Segel's mum hated his nude scene in 'Forgetting Sarah Marshall'.
The 34-year-old actor has revealed that his mother failed to laugh when she first watched the scene where Jason gets naked in front of co-star Kristen Bell.
Talking to The Guardian, Jason - who played Peter Bretter in the 2008 rom-com - joked: ''Poor mum, I really misjudged that. I thought we had this connection. I thought she would find the surprise of it funny. But she really did not.''
The Hollywood funnyman also stars opposite Cameron Diaz in his new film, 'Sex Tape' and he explained to the newspaper that he took on the role because he wanted to feel ''challenged''.
He shared: ''I needed a part where I felt I was being challenged. I had to step it up and play a man.
''The era of me playing a man-boy who really needs to grow up is gone. Things have changed.''
Despite a string of successful films and the hit TV show, 'How I Met Your Mother', Jason has remained very humble as he told The Guardian that he's not naturally good at acting.
He said: ''I act and I write. I produce and write songs. But it's not like I'm naturally good at any of those things, it's just that I've been prepared to sit in the learning curve. In the end, we're all guessing.''
