Random Trivia For This Title:
- The scene with Chekov and Uhura asking passerby where Alemeda and the U.S. Enterprise were was completely unscripted, as was the young lady's clueless response, "Ooh, I don't think I know the answer to that one - I think it's in the bay, in Alemeda." Crew had to chase her down after the shot was taken to get her to sign a SAG waiver and permission to use her in the film.
- When the alien ship is approaching Earth at the beginning to look for the humpback whales, there were originally subtitles saying things like "Where are you? Can you hear us?".
