Logan's Run (1976) - 11 mistakes

Visible crew/equipment: Near the beginning when Logan and his friend come up the escalator, you can see the reflection of the film crew on the mirror behind them.

Continuity: When Jenny Agutter panics after a lizard crawls up her skirt, her clothes are very dirty but in the next scene, her clothes are clean.

Revealing: When Francis emerges from the cave, he stands in the foreground, with the distant mountains and sun in the background. The sun creates a lens flare, which is an internal reflection within the camera lens. Yet Francis is in front of the flare. This shows that the actor was composited with the background via a traveling matte process.

Continuity: When Logan and Jessica arrive at the ice cave, they are wet, so they take off their clothes and wrap themselves in animal skin to get warm. Jessica gets naked and Logan takes off his shirt but not his pants. But when they sit down we can see he is not wearing any pants.

Revealing: In the carousel scene, when the contestants are starting to float into the air, you can see the cables attached to the contestants that are lifting them up.

Continuity: When Logan 5 and Jessica 6 are escaping from the city, Jessica's hair is wet before she passes besides the flowing water tanks.

Visible crew/equipment: When Logan and Jenny Agutter meet the shiny robot in his ice lair, you can see the reflection of the film crew many times on the shiny body of the robot.

Continuity: When York and Agutter finally escape from the robot's ice lair to the outside world, they see the sun rising from the horizon. The sun rises far above the horizon but a few shots later, the sun has gone back down near the horizon.

Continuity: When Doc says, "Pay attention Sandman, I'm proud of this machine" the Anodyne and Kinesis levers in the background are in the down position. The camera cuts to Logan and back to the Doc and the levers are now in the up position.

Continuity: At the end of the film, when everyone is gathering around the old man, there are several close up shots of him. In one of them, a woman in pink starts walking up behind him, near the right side of the screen. In the next shot, the camera shows a faraway view of the old man and where the woman was standing, but she is gone.

Revealing: When Logan shoots at the first runner, his two shots hits the ground in front of the runner but you can see the setup on the ground that explodes and creates sparks.
