The Muppet Movie takes it upon itself to be all things… well, two things. It has to be appealing to kids and adults. The film is split roughly in half between the audiences, with the adults having more to appreciate in the star cameos–some cute, some hilarious (Steve Martin in short shorts)–and terrible puns and the kids have the songs.

To keep the kids amused during the more “adult” parts, there are the Muppets. The level of puppetry on display here is staggering, particularly once one realizes only a couple of the Muppets have moving eyes. The others just give the impression of moving, lifelike eyes through head tilts and reaction motion. Jim Henson and the Muppet performers show a masterful understanding of how the slightest motion implies real animation.

But the adults also have to be kept amused during the song sequences, which is a little harder, even though the Paul Williams and Kenny Ascher songs are great. There’s occasional humor, but there’s also amazing filmmaking. Director Frawley does a great job, as does Isidore Mankofsky’s photography and Christopher Greenbury’s editing. The Muppet Movie‘s beautifully made… and they know it.

The script frequently breaks the fourth wall, including references to how great some of the previous shots came out. The only bad shot is during Dom DeLuise’s cameo, like his close-ups had to be reshot.

The film’s idealistic and infectious. If you can believe the Muppets are real… you can believe in the film’s positive, inspiring message.
