Continuity mistake: In the sequence where Hanjuro crashes the helicopter, the pilot disappears and reappears at random. (00:09:15)
Suggested correction: Actually no; he's still there even in the camera angle the second screenshot is from; the knee of the policeman that is fighting Hanjuro covers his head, and then the seat makes it impossible to see him again. You may have to slo-mo to spot it, but he's visible at the beginning of the shot.
Other mistake: Mace's reflection can still be seen on the pond after he disappears. (00:53:30)
Suggested correction: This isn't a mistake. That's him, under the water in the same pose he was in before he touched the water.
After watching the scene, the mistake is valid. When he's underwater, he's not in the same "pose." That would require him to be upside down and squatting. But that's not the pose we see him in.
We see Mace semi-kneeling and reaching out to touch the water when he vanishes, but his upside-down reflection is still in the exact same calm position even when he's gone, and in the next shot we see Mace under the water right-side up, with his arms reaching up to the surface. This is a valid mistake, the suggested correction is not right.
Continuity mistake: Sheena goes barefoot most of the movie but near the end when she's riding a zebra she's wearing a pair of sandals which disappear a few minutes later.
Continuity mistake: The note Jenny puts up in the restroom changes; when Starman goes into the bathroom while Jenny is signing the receipt, notice that the postage stamps holding the note to the mirror are now in different positions and the word "help" is smaller. (00:35:55 - 00:36:45)
Continuity mistake: The first car he jacks is a white 4 door Oldsmobile Cutlass salon, and a 2 door Olds Cutlass Supreme in the next. (00:09:30)
Continuity mistake: When Elaine gets knocked out with the ball her hat falls to the ground, next to her car. When the boy drives off the hat is gone. (00:12:55)
Continuity mistake: At the beginning of the film, the young Roy breaks a board of the hen-house wall with a pitch. When the shot cuts back to the hen-house wall a moment later, the hole is a different shape and in a different place.
