Speaking at a press junket for The Five-Year Engagement, Muppets co-writer Nicholas Stoller updated Collider on the progress of The Muppets sequel. Things are moving fast!

For starters, the script is already in the process of being written. They hope to have the film in theaters by next summer, but Stoller believes Disney’s plan may be a bit too ambitious.

What else was learned? From Collider:

Q: I love the first one. You mentioned comedy caper. Obviously the Muppets have done a lot of stuff. Are you looking at any of the previous Muppet movies or is this a whole new angle on what you guys are doing?

Stoller: Yeah, I think it’s similar to the first one in that the first one certainly had dramatic connections to the first Muppet movie, but it was a whole new thing, hopefully. This is the same thing. We love The Great Muppet Caper and we love Muppets Take Manhattan and whatnot. So this has some elements of that, but it’s different because it’s in the tone of what James and I like to do.

Stoller goes on to say that they do plan on introducing new characters for the sequel, and that Jason Segel may make a cameo.

We had learned last month he wouldn’t star in the film because his prior commitments won’t allow it.
