After a long (and pretty spectacular) marketing campaign that saw the loveable characters take on everything from Twilight to The Girl with the Dragon Tattoo, Disney’s The Muppets is finally hitting theaters next week. However, it was an even longer road for the actual production of the film to come to fruition. A self-professed Muppet fanatic, Jason Segel was hired to co-write the script with Nicholas Stoller fresh off their success on Forgetting Sarah Marshall. When it came to casting the film, they had their sights set on Amy Adams. However, with the Muppets at their disposal, Segel and Co. asked Adams to be a part of the movie in a delightfully unconventional way.

Hit the jump to check out the video that Segel sent to Adams asking her to join the cast. The film also stars Rashida Jones and Chris Cooper. The Muppets opens November 23rd.

I have to admit that there is no film that I was more excited to see this year than The Muppets, and it definitely did not disappoint. Far exceeding even my high expectations, it turned out to be one of my favorite films this year. Having grown up on The Muppets, I never could have imagined that I would someday get to to interview Kermit the Frog, Miss Piggy and Walter, who is introduced in this film, and it will remain one of the most memorable experiences of my career.

During the interview, Kermit, Piggy and Walter talked about what The Muppets have been doing for the last 20 years, whether or not Kermit had script approval, who designed Piggy’s wardrobe, how Walter got cast in the film, what it was like to sing “Rainbow Connection” again, how famous The Muppets are for pulling pranks on set, doing their own stunts, and the advice Kermit gave Walter on dealing with his sure-to-be adoring fans.
