Trivia: Ultra Magnus was suppose to die in a different way at first. The sweeps fired long laser beams that looped round him, and then they all flew off in different directions, ripping Ultra Magnus apart. Censors forced the artists to change it since it was to violent for a kids movie. However, you can still see the Sweeps fire the long laser beams, but when the shot changes lots of little laser blasts his Ultra Magnus.
Trivia: A trailer for the Japanese movie has been found that has a lot of unused footage on it, and can be downloaded off www.seibertron.com The unused footage includes a lot of extra animation for the part where Unicron eats his first planet, Ultra Magnus in different colours, a shot of Autobot City's defences firing at the Decepticons, a shot of the Decepticons avoiding fire (but Skywarp takes a hit), a very different looking Autobot city, unused shuttle footage (with Arcee and Daniel on the same ship as Hot Rod, Kup and the Dinobots) etc. It is believed that this was originally "test" animation to see how the movie could look.

Trivia: The movie marks the first ever appearances of Blaster's cassette transformers. However, originally they were suppose to be different designs. There was only 1 robot, called Bolts. The other three with animals. Cubbie was a lion, Stinger a scorpion, and Stripes a tiger. They were changed later to two robots and two animals, a rhino and a lion.
Trivia: This film was originally intended to be part of a double feature with the movie version of the cartoon series "G.I. Joe" ("Action Force" outside the U.S.). In both cases the makers were granted permission to kill off the majority of the cast so that new characters (and therefore new toys) could be introduced to carry on the storyline. Transformers was the first to be released to a veritable onslaught of negative feedback (possibly due to the slight technicality that children don't like seeing their favourite characters die). This prompted a massive overhaul of the G.I. Joe movie with the result that in the finished film, many of that series' main cast sustain the same level of injuries that Optimus Prime and others suffer, only they just lapse into comas.
Trivia: It seems like nobody knows if Orson Welles (who died before the release of the film) did complete all of his lines. This is because even official sources don't seem to know if he did. Take the Transformers Series 2 Part 2 DVD set. This has a quiz on it and one of the questions goes something like "Orson Welles was unable to complete his lines in Transformers the movie, who completed them for him?" The only correct answer is Leonard Nimoy. However other official sources say that he did complete his lines, such as the voice actor for the character Arcee, who said she thought that Welles had done all of his lines.
Trivia: When the Decepticons retreat to Astrotrain, if you watch really carefully as Astrotrain transforms from train to space shuttle mode, he will do a 360 degree turn. Surely the Decepticons inside will be a bit unsettled?
