Short Circuit (1986) - 34 mistakes

Continuity: When Johnny 5 nearly drives the snack wagon over the edge to where it is hanging, it appears to have miraculously moved right back from the edge, making it look like he never went nearly over in the first place.

Visible crew/equipment: When Newton is playing with the robot arm and the piano you can clearly see wires attached to the top of it controlled by the puppeteers.

Continuity: When Number 5 gets out of the truck it is no longer hanging over the edge of the cliff. It has moved inland by several feet.

Visible crew/equipment: You can see a wire attached to the back of Stephanie's truck in this scene, which obviously stops it from really falling over the edge of the cliff.

Revealing: When number 5 is leading number 3 in to the toilet and moves at the last minute you see number 5 falling over but in the next seen hes perfectly fine.

Plot hole: Number 5 picks up mud and throws it at number 1's face. But from there on, Number 5's hands have no mud on them. We never see Number 5 clean his hands, so were did the mud go?

Revealing: When Frank takes the orange juice from the tray Johnny 5 is holding, the tray moves with the glass for a second. This is because the orange juice glass was glued to the tray, so Johnny wouldn't drop it.

Continuity: The amount of mud on number 1's face changes to nearly nothing to loads.

Continuity: Just after Stephanie's truck stops on the cliff edge, she gets out and goes to talk to Ben and Newton who were following her in their Nova truck. She goes around the back to talk to Ben, and sees him taking Number 1 out. In the first shot of here her arms are by her sides, but when the view cuts to a different angle, she has her right hang on the side of the van door.

Continuity: Johnny flicks around the radio stations and tunes into 94.1 and there is some music - he tries another station and then comes back to 94.1 and it is already into the first chorus of the "Who's Johnny?" song.

Continuity: When Johnny gets scared of Stephanie's dog, he moves backwards and falls off the porch onto the ground below. His actual framework stays in the same position, but the tracks he uses to move around are strangely upside down. The tracks are made up of long black rectangles with curved edges on the top, but when we see Johnny lying down, the shaved corners are at the bottom.

Other: The tree used to hold up Number 2 is very thin and weak looking, yet it supposed to be supporting a 400lb robot. Strong tree.

Continuity: In one of the first scenes where the robots are being tested on the fake tanks and trucks, you see the robots' lasers being raised from the front. The front of the lasers come up into firing position as opposed to lowering into position. This is not possible considering the lasers are mounted on their backs and the front of the lasers lower into firing position in the rest of the movie.

Continuity: The scene where Johnny falls off the bridge, opens his parachute and lands in Stephanie's truck is obviously fake. Johnny doesn't move, yet all the backgrounds do - the scene was obviously filmed infront of a blue screen.

Other: When Johnny is changing his arm in the back of the Nova truck, it's quite obvious that the new arm he 'attaches' isn't realy attached at all.

Revealing: After Johnny blocks the gunshots from Frank, he begins to flip a coin and imitate John Wayne. You can see the thin wire connected to the coin on the left side of it.

Visible crew/equipment: When Number 5 plays with the light switches on the way to the disarming section, a coffee serving robot comes through the corridor, and the reflection of the camera is visible in the coffee pot.

Visible crew/equipment: When number 5 falls off the bridge you can see a thin rope attached to him, either used to activate the parachute, or used as a guide wire to keep the robot stable while falling.

Continuity: When Ben unloads Number 1 from the truck, it is almost fully erect, yet in the next shot, it is in a crouched position.

Continuity: When Johnny is exploring Stephanie's house we see 3 shelves in the background and on the middle shelf is a grey cat. In the next shot there is a black and white cat in its place.
