events in New York City. On July 3, 1978, Henson flew to Los Angeles again to begin shooting for the film. Filming Principal photography began on July 5, 1978, and continued for 87 days during summer and fall of that year. Each minute took a day to be filmed. Filming locations included Albuquerque, New Mexico as well as various parts of Los Angeles and Northern California, including San Fernando Valley. Additionally, the interior shots were filmed at CBS-MTM Studios. All of the sets were elevated by five feet to allow the puppeteers to perform. Austin Pendleton recalled that the film was shot on "a very unhappy set, because Jim [Frawley] was very unhappy directing that movie. And I noticed that was the only time the Muppet people used an outside person to direct a Muppet movie. They never did that again. After that, it was either Jim Henson or Frank Oz. And I would have liked to have been in one of those, because those sets were very harmonious. But this was not." According to Henson, shooting the movie was slower than in television. No effects were added after filming concluded. Several shots required Muppets standing and acting in a full-body shot. To perform Kermit sitting on a log, Henson squeezed into a specially designed metal container complete with an air hose (to breathe), a rubber sleeve which came out of the top to perform Kermit and a monitor to see his performance, and placed himself under the water, log, and the Kermit puppet. He was also assisted in this operation by Kathryn Mullen and Steve Whitmire. During breaks, cups of ice tea were given to Henson through the rubber sleeve since he could not easily leave the tank. Rescuers had to stand by the tank to pull Henson out if the tank leaked or the air supply had difficulties. The scene took five days to be filmed. To have Kermit ride a bicycle in a full-body shot, a Kermit puppet with legs was posed onto the seat and his legs and arms were attached to the pedals and handlebars. An overhead crane with a marionette system held the bicycle through strong strings invisible to the camera, guiding the bicycle forward. The crane and system were out of the camera's frame of vision. Specially made, remote-controlled puppets were placed on the set and controlled by puppeteers out of the frame.
