* AlternateCharacterInterpretation: Did Maximillian abandon Dr. Reinhardt at the end, or did he just not have the ability to send the elevator back up? Either is possible for such a cold and murderous machine.
** Another possibility is that Reinhardt already gave him orders to stop the heroes, and he can't help Reinhardt until he completes the task he was already given. Of course, he then drops that task entirely to fight [=V.I.N.CENT=].
** For that matter, Reinhardt mutters "protect me from Maximillian" at one point; he may just be trying to play the sympathy card on Kate, or Max may really be the one in charge.
* EverybodyIsJesusInPurgatory: In the finale, we see [[spoiler:Reinhardt merge with Maximilian in Hell and then we see a spirit heading for Heaven. Someone assumed that since Reinhardt had killed Frank [=McCrae=] for his own nefarious purposes, he's condemned to Hell in [=McCrae's=] place, and the spirit is actually [=McCrae=]'s being redeemed.]]
** The movie clearly [[ShoutOut owes more than a little]] to ''Film/ForbiddenPlanet'' (a space crew encounters an arrogant bearded scientist with a secret who is the last survivor of a space expedition, and is now hanging out with a hulking robot he built), but the most thematically notable parallel is that Maximilian is Reinhardt's dark alter ego, his [[Film/ForbiddenPlanet id monster]]--the robot is named after Reinhardt's actor, for goodness's sake. At the end, [[spoiler: Maximilian merges with Reinhardt, and Reinhardt finds himself [[FateWorseThanDeath trapped inside his evil self in]] {{Hell}}.]]
* FridgeBrilliance:
** The ending may be more straightforward than we think. After all, [[spoiler: assuming there is an afterlife, plunging into a black hole certainly will send you there, one way or another.]]
** Rather coincidental that there'd be a funeral on the very day that the ''Palomino'''s crew arrived, isn't it? [[spoiler: Maybe not: it's entirely possible that Reinhardt turned the murdered corpse of Frank [=McCrae=] into one of his automatons, then had the man's mindless shell destroyed when he realized Kate was among the new arrivals and might recognize her father's gait and posture.]]
* HilariousInHindsight:
** V.I.N.CENT looks remarkably like Cartman from ''WesternAnimation/SouthPark''.
** The fact that the film was made to ride off the coattails of films like ''Franchise/StarWars'', in light of the fact that Disney now owns the franchise in question.
** The film's plot bears some strong similarities to the later film ''Film/EventHorizon''.
* IdiotBall / SomethingWeForgot:
** Reinhardt would've avoided so much trouble if he had just remembered to keep [=B.O.B.=] out of reach from the Palomino crew instead of letting it become pals with [=V.I.N.CENT=] and telling it what actually happened to the crew of the ''Cygnus''...no one else on the ship could have told them anything, since they're all robots without speech capability.
** In the novelization, B.O.B. explains that Reinhardt and Maximillian missed reprogramming him to be obedient, as they did all the other robots on the ship, because he was deactivated [[spoiler: during the mutiny]], and he has survived with his personality intact since then by acting like he had been reprogrammed.
* SpecialEffectFailure: The special effects are pretty good for the era[[note]]and at the time, better than films like ''ANewHope'', ''Film/{{Superman}}'' or ''Film/{{Alien}}''[[/note]], but there are a few mistakes:
** The strings holding up the flying robots are very visible in some scenes (like BOB's first scene in parts storage).
** In the funeral scene, the humanoid robots on the very edges of the room have the tops of their heads cut off by the matte painting of the room's walls as they walk out, which rather gives away where the set ends and the painting starts.
** Some of the "meteors" are visibly transparent as they fly around the ''Cygnus.''
* WhatDoYouMeanItsNotForKids: This was the first Disney movie to bear a PG rating. This trope ultimately led to the creation of Creator/TouchstonePictures, to deal with more adult fare. Further, there was no PG-13 rating until 1984, meaning that PG included everything just short of being rated R (other films that were rated PG include Film/IndianaJonesAndTheTempleOfDoom (yes with the hearts getting ripped out) and Film/StarTrekIITheWrathOfKhan (with the mind-controlling parasites that crawl in your ear and the murder victims hanging from the ceiling).
