Amy Adams agreed to take part in 'The Muppets' after Kermit the Frog asked her.

The actress appears alongside Jason Segal in the new movie based on Jim Henson's creatures and while she has always been a huge fan of the series, being asked by the famous green character was the deciding factor in taking on a role in the film.

She explained: "This is something I grew up with and was in love with. When I heard they were doing a new one I was really excited. Jason sent me a DVD where he and Kermit were inviting me to be part of 'The Muppets'. It was really cool. Once Kermit asks you to do something it is really hard to look at him and say, 'No.' So I was hooked!"

However, Amy admitted to feeling huge pressure after she realised she was Jason's first choice to star in the film with him when he wrote The Script.

She explained to the website Popsugar: "I didn't know the extent to which he had thought of me. I knew for him to send a personal invite to be a part of it and getting Kermit to be a part of it - I knew that he was serious about it. I didn't know that he specifically had me in mind until I after I was on set. It's a lot pressure and I didn't know!"
