Collider had a chance to talk to Jason Segel who had this to say on not returning to do a new Muppet film:
"My goal was to bring The Muppets back and I did that leaving them in very good hands, my writing partner and James Bobin the director. All I wanted to do was to set the stage for them to do whatever they wanted. I did what I set out to do, and now I wanna pursue more human-related projects. I’m sure I’ll return in some capacity here and there, but that was half a decade of my life. Five years of hard work. I’m ready for a little puppet break.”Check out Bret McKenzie's Academy Award winning song "Man or Muppet?" from the film, also below are DVD bonus features:
