Trivia: One very unusual filming location used in the movie - the Budweiser Brewery in Van Nuys California. When Kirk wakes up in sickbay he runs through the ship and finds Uhura in a room with several large horizontal silver tanks. These are the lagering tanks that contain the chips used for beechwood aging. The engine room looks like a factory filled with huge vertical tanks. In the movie they supposedly contain engine coolant; in reality they are Budweiser's primary fermentation tanks where yeast is added to turn sugar into carbon dioxide and alcohol.
Trivia: The Planet Delta Vega on which Kirk is marooned by Spock is a reference to the original series episode "Where No Man Has Gone Before" in which Kirk was faced with the choice of marooning his friend Gary Mitchell on the deserted planet Delta Vega after Gary obtained Godlike powers and became a threat to the Enterprise. That Delta Vega was close the the edge of the Galaxy however, not near Vulcan, which is 16 light years from Earth.
Trivia: The Vasquez Rocks Natural Area Park in northern Los Angeles County, California, was once again used to depict the surface of Vulcan, as it was in the movie Star Trek IV: The Voyage Home (1986). The Vasquez Rock was also used in the "Arena" episode of the original series. The rock formations were named after a bandit that used them to elude capture in 1873.
Trivia: When the crew is discussing the possibility of an Alternate Reality, Spock says, "When you have eliminated the impossible, whatever remains, however improbable, must be the truth." This is actually a quote from Sherlock Holmes, found in The Sign of Four. Spock also says the same line during the investigation of the Klingon Chancellor's death in "The Undiscovered Country".
Trivia: This is Leonard Nimoy's first live-action feature film since Star Trek VI: The Undiscovered Country in 1991, and the first time he has played Spock since that film, as well; his appearance in a two-part episode of "Star Trek: The Next Generation" pre-dated the film's release by a week.
