Star Trek IV: The Voyage Home/Trivia


 * Defictionalization: within 3 years of this film coming out, there was a formula for transparent aluminum.
 * Throw It In: "I think it's across the bay, in Alameda." Not written in, but Nichols and Koenig just stayed in character when an extra said it. See here for details.
 * Leonard Nimoy was trying to crawl out of the water during the final scene, but the rest of the cast members just dragged him back in.


 * What Could Have Been: Eddie Murphy was originally going to play the marine biologist Kirk interacts with. He eventually backed out of the movie but it resulted in a massive change to the storyline. The producers were worried that if Murphy was in the movie it would turn into a guest star movie like Superman III became Richard Pryor's movie. So they made sure the biologist character was clearly a secondary character to Kirk and Spock.
 * You Look Familiar: Brock Peters plays Admiral Cartwright and would go onto play Joseph Sisko on Star Trek: Deep Space Nine.
