Transformers: The Movie (1986)

Continuity mistake: When the Decepticons get into Astrotrain, there is a sort of semi-circle shaped space to get through, but when it shows Astrotrain's door closing, there is no semi-circle, just a big space.

Continuity mistake: When Ratchet gets shot in the shuttle attack scene, the red cross on his arm vanishes.

Other mistake: The credits for the movie say that they are in alphabetical order, but Peter Cullen is listed before Scatman Crothers.

Continuity mistake: When Hot Rod goes next to Prime and says "Optimus....forgive me," the aerial things on the side of Prime's head are grey instead of blue.

Continuity mistake: When Daniel finds Spike inside Unicron, the control panel he uses to convert his arms to blaster mode is already open and 'active'. Seconds later Daniel opens and then activates the panel even though it was already open to begin with.

Continuity mistake: In the scene where Hot Rod and Kup are stuck underwater, we see Hot Rod fighting a Giant Squid. Just after the Giant Squid swims off we see a shot of Kup lying on the ground with his right arm and his left leg missing. However, when Hot Rod gets to him they have swapped sides, the left arm is missing and the right leg is missing (don't be confused by the fact Hot Rod flipped him). Only two of Kup's parts are missing, as we only see Hot Rod pick up two parts.

Continuity mistake: When Prime first transforms (after he says "Megatron must be stopped- no matter the cost") his trailer is missing its Autobot symbol. In the immediate long distance shot that follows, the symbol is visible.

Continuity mistake: During Galvatron's attack on the junk planet, you see a glimpse of Shrapnel and Scrapper, who were previously transformed into the Sweeps by Unicron.

Other mistake: When Devastator throws a piece of the wall during the attack on Autobot city, his face is completely blacked out. Looks like they erased it and forgot to draw it back in.

Continuity mistake: When Springer backs away from Wreck Gar at the part where the Junkions attack, Springer is suddenly missing his Autobot symbol.
