This film marks the first time that Janice speaks since the death of Richard Hunt (another of Hunt's characters, Scooter, had a line in Muppets from Space (1999), which was voiced by his brother Adam Hunt).
This is the first Muppet movie where Eric Jacobson does Frank Oz's roles of Fozzie, Piggy and Animal. (Sam The Eagle is performed by Kevin Clash). Frank Oz has been inactive in the Muppets lately to pursue directing.
Originally, this movie was first broadcasted on NBC. Many references to the network are made throughout the film. Whenever this movie airs on other TV stations, all the NBC references are cut from it, but they all remained intact on the DVD.
Jerry Nelson was sick during some of the production of this film, and only was able to spend limited time performing (he performed a lot of his Statler scenes, and some Robin scenes), some scenes were dubbed (Pops, the Announcer and Floyd were all dubbed), or performed by someone else (Bill Barretta performs Lew Zealand).
Steve Whitmire, who was beginning to perform Statler around this time, puppeteered him while his current performer, Jerry Nelson, was out sick. Nelson later looped Statler's lines, but one of them ("Historical landmark!") remained unlooped.
