Deliberate mistake: It's not particularly believable that the away team to stop the assassination would consist of the ship's entire senior staff, and raises the question of who was left in charge of the bridge (the answer: apparently nobody, as they return to a completely deserted bridge). Of course this is dramatic license, and at this point the audience won't care or likely even notice.
Star Trek VI: The Undiscovered Country (1991)
1 deliberate mistake - chronological order
Directed by: Nicholas Meyer
Starring: Christopher Plummer, William Shatner, Kim Cattrall, George Takei, Leonard Nimoy, Michael Dorn, Walter Koenig, DeForest Kelley, James Doohan, Nichelle Nichols, Kurtwood Smith, Brock Peters
Continuity mistake: When Captain Kirk and the shape shifter are fighting on the planet (the shape shifter looks exactly like Kirk). They are rolling through the snow about to roll over Bones. In one shot, it looks like they will roll over his feet first, and then the rest of his body. In the next shot, it is a little closer and they roll over Bones' right arm first and not his feet first.
Captain James T. Kirk: Spock, you want to know something? Everybody's human.
Captain Spock: I find that remark... Insulting.

Question: Is it my imagination, or does the opening theme sound similar to the classical piece "The Planets - Mars" by Holst?
Answer: At one point Nicholas Meyer did indeed have the idea to incorporate "The Planets" into the score, but apparently the rights proved too expensive. I have no doubt Meyer asked composer Cliff Eidelmann to give the score a similar sound.
Chosen answer: There are certain similarities, yes. Whether any specific aspects of the piece were deliberately incorporated into the film's opening theme is an open question, but the overall feel is undoubtedly very similar.
