The Muppet Movie (1979) - 13 mistakes

Visible crew/equipment: In the scene when Kermit confronts Doc Hopper he comes walking out of the bar. If you look at the top of Kermit's legs when he walks out, two pair of hands can be seen moving the legs.

Visible crew/equipment: When Kermit and Fozzie are driving to Hollywood, the reflection of the camera and the cameraman's hand are seen in the mirror.

Continuity: In the scene where Kermit, Fozzie, et al are following Gonzo, who is floating from the helium balloons, Fozzie opens his door and looks up at Gonzo. When he comes back into the car after Kermit shouts at him to do so, the steering wheel comes loose from the dash and all the muppets start yelling. In the next shot of the interior, the steering wheel is back in place. I do feel maybe this was a flub that was left in on purpose, because it was so funny the way all the puppeteers ad-libbed a reaction to what shouldn't have happened, but it fails in continuity because in the next shot the wheel is fine.

Audio problem: Fozzie and Kermit are driving right towards Gonzo and Camillia. When Fozzie says, "Yeah, cute huh?" if you look in the mirror, his mouth doesn't move.

Continuity: When Gonzo is flying in the air holding on the balloons and then is shot down by Doc Hooper and lands on the car, the last two balloons are yellow and pink, but when the car takes off after Gonzo lands on the roof – the two balloons are now both blue.

Visible crew/equipment: When the Electric Mayhem Band has finished painting Kermit and Fozzie's car, you see the newly painted car and the band walks into the shot, you can see the head and hand of the puppeteer who is operating Scooter.

Visible crew/equipment: In the scene where Kermit meets Fozzie, when Fozzie tosses the rubber chicken over his shoulder you can see Frank Oz's arm and where the glove ends.

Continuity: Kermit's ice cream in the fair scene changes colour.

Other: Whenever Fozzie is driving the Studebaker, the movements of the car don't correspond to the way he moves the steering wheel (he tends to crank it back and forth a lot).

Visible crew/equipment: When Kermit is on his bike and enters the site of the Doc Hopper's Frog Legs Restaurant, look closely at the bike. You can see the wires moving the pedals of the bike; one behind Kermit and one by the basket. Try to look for it when he rides by the black truck.

Other: In the fight scene right after Miss Piggy blasts the man through the wall, she kicks another man. If you look closely, he goes back from the kick a little, then just stands there and adjusts his hat.

Other: When Sweetums scares the girls out of the tent, watch the first girl that runs out screaming. If you look at her face closely, you can see that she is smiling.

Continuity: When Kermit and Fozzie come round the corner and see the billboard with Kermit's face on it, you can see that there is nothing behind the billboard. Yet later when Doc Hopper and Max are leaving, Hopper's car is behind the billboard. The car slightly sticks out, so Kermit and Fozzie should have seen it.
