Jason Segel has landed his dream job on the Muppets movie - and he's determined to get it right.
The How I Met Your Mother star wrote and produced the film, in which he stars alongside the much-loved puppets, but admitted his first day on set was filled with trepidation.
"You feel, from my position as co-writer and producer, like 'Boy, I'd better not mess this up'. These are like my idols and I'm involved in somehow trying to do justice to that legacy," he said at Disney's D23 fan expo in California.
"It was scary and very daunting, but I really feel like we did a great job."
Jason wants The Muppets to mark a return to old-fashioned values, which will see his character Gary trying to reunite with the famous puppets after they're disbanded.
"Humour these days has become cynical and sarcastic and mean-spirited and that's never what the Muppets were," he continued.
"If you've grown up with the Muppets, as soon as you start writing in those characters' voices... nothing mean can come out of your mouth, it just doesn't happen. You try to write Kermit saying something mean, and it's wrong, instantly. I think that says a lot about the Muppets and this movie really holds true to that spirit."
Alongside the likes of Kermit and Miss Piggy, The Muppets - due out next year - will feature Amy Adams and Chris Cooper.
