Jason Segel: 'The Muppets is pure, sweet and innocent'

Jason Segel has described starring in The Muppets as a dream come true.

The actor, who co-wrote The Muppets, explained that working with Kermit The Frog and Miss Piggy was a nice change of pace from his more adult roles in Forgetting Sarah Marshall and Bad Teacher.

"The Muppets movie is right in my wheelhouse. It was nice to do something that was really pure and sweet and innocent," Segel told Reuters.

He continued: "It's sort of a trade off. You can't do the raunchy jokes, but you get to do these totally Muppety jokes that you don't do in regular films. It was a fair trade off for me."

Segel went on to name Kermit The Frog as his very favourite Muppet, saying: "I remember watching Kermit and thinking, 'That's who I want to be when I grow up'.

"He's Tom Hanks, or Jimmy Stewart. He's the moral compass of the Muppets and he's the every man, the glue that holds it all together."

Segel previously joked that he's hesitant to become a father because his large size often frightens babies.

The Muppets is released in theatres in the US on November 23 and on February 17, 2012 in the UK.
