Visible crew/equipment: When Alan and Lora go to see Kevin Flynn at his game room they find him playing his videogame 'Space Paranoids'. After he finishes playing, he turns around to talk with Alan and Lora. As they are speaking you can see the microphone coming up from the bottom of the screen. It even hits Kevin Flynn in the hand.
Continuity mistake: Tron sends his memory disk to talk to Alan. After Tron communicates with his user Alan1, Alan sends him back the disk with new data on it to destroy the MCP. When Tron receives the disk it is like a Frisbee, solid on the top and hollow on the bottom. When he receives the disk the hollow part is on the bottom. He holds the disk in front of him and starts talking about "the key to the new order". The shot changes and the disk has been reversed, hollow side toward him and solid side away from him. He did not have time to rotate the disk. (01:08:10)luchador
Revealing mistake: After Flynn, Tron and Ram take their drink, they resume their journey in their stolen Light Cycles. There is a shot of them coming around a corner and riding along a cliff side. If you look carefully (this is painfully obvious if you go frame by frame) they don't actually come around the corner. Their Light Cycles simply appear one by one and they make their turn.

Continuity mistake: When Tron fights off Sark's men as they board the Skyship, watch for the soldier who falls off the side just after Flynn. It's obviously a still rather than an actor as only a pair of non-moving legs fly past the ship. It's an editorial mistake as had the character been "derezzing" (deresolution) he would have glowed yellow and faded which did not happen here.
Deliberate mistake: The text the Master Control Program speaks in the human world is usually accompanied with a text projected on a computer screen. When Flynn attempts to hack into the system through the laser lab terminal, the Program is cut short at 'I'm afraid you.' (both on the screen and in speech) as Flynn progresses. In reality, however, it should be that the full text intended to be relayed by the MCP should be displayed on the screen, and only the speech gets interrupted. (00:29:40)
Continuity mistake: In the initial Lightcycle scene, the bikes inexplicably change position: In the beginning, Sark's blue cycle is on the left, but after they turn towards the arena wall - just before the user worshipper crashes - Sark suddenly races on the right side; and there is no sign that he changed tracks in between shots. (00:01:20)
Factual error: When Alan gets the message that his security had been suspended at Encom, the computer gives a Date/Time stamp of Sept 22, 18:32:21 PM (6:32 PM) But at the time, it is shown to be pitch dark outside. Isn't 6:32 PM early to be completely dark outside in mid September (keeping in mind that no matter how far east one is, it can never be full dark outside at that time, at that period of the year). Also, why would the Time stamp have "PM" in it when it is using the 24-hour clock? (00:10:40)
Continuity mistake: When Flynn, Tron, and Ram are in the lightcycles, most of the time the cycles are red, yellow, and orange. However, in one shot where the 3 of them have left the game grid and are speeding away from their pursuers, the cycles are shown as red, yellow, and green. [This has been corrected in the special edition re-release.].Aerinah
Revealing mistake: When the first of the blue bikes hits the wall and makes the hole, there is a rubber tyre bouncing away from the explosion. Any time that you see the back wheel of the cycles, there is no rubber tire. This is supposed to be the digital world. Even the tanks, with all the accompanying sounds does not have rubber on the tracks, as there are no tracks.Movie Nut
Continuity mistake: From the Light Cycle grid, the hole in the wall made by one of the Blue bikes has a jagged side like the teeth of a saw blade on the left side, and a couple of squared projections on the right. The hole goes all the way through to a tunnel on the other side. When the trio escape, and exit out into the tunnel, the hole has the saw-tooth jagged side on the left instead of the right. It should be a mirror image of the Grid side of the hole.Movie Nut
Other mistake: In the Ring Game, Flynn throws a shot that Crom catches and returns. When the shot hits Flynn's rings, it takes out the third and fourth ring. Problem is that any other time, the impact only takes out the ring that it hit. Close inspection shows a solid hit on the fourth ring only. The only explanation is that since Flynn continues and jumps the "gap" in the rings, this was a deliberate set up to bring the end to this sequence and move the movie forward.Movie Nut
Continuity mistake: When Alan is typing to get access to TRON, his hands are reflected in the screen. When he's done typing, his hands and then his arms move back to a relaxed position. When the camera cuts to his face you can see his shoulders move as his arms are pulled back from the computer to a relaxed position again.Movie Nut
Revealing mistake: When Alan gets up to go to see Dillinger, look at the cubicles. The first row that Alan came out of is real. In the immediate next row, the cubicle that is adjacent to Alan's has no visible exit, and the two that would be heading toward the white wall seem to be only leading to each other. The rest of the cubicles in the area are all a matte painting used to extend the set.Movie Nut
Revealing mistake: With the exception of the set up and ending "real world" sequences, this is all in the digital world. There is no sun, yet when Tron, Flynn and RAM are drinking at the pool of energy, there is a reflection of what appears to be a plaza and a bright day outside the windows.Movie Nut
