Twilight star Taylor Lautner feared he would flop as a funnyman when he joined British sitcom Cuckoo.

The Hollywood star, known for his action roles, signed on to replace Andy Samberg in the show, but he was gripped with anxiety amid concerns his comedy chops were not good enough.

He tells British newspaper The Sun, "I wasn't confident at all. I'd only done cameos in comedy films before and hosted Saturday Night Live but this was my first fully fledged comedy. It was a big risk for me but I'm so glad I did it."
