Trivia
Eddie Murphy was originally planned to take the role of the 20th Century Terran who assists the Enterprise crew in their efforts to retrieve the Whales. He would have played an English teaching college professor who believes in extra-terrestrials and witnesses the Enterprise crew's arrival when they materialise above a football game being watched by Murphy. While everyone else believed it to be a special effect for the game, Murphy would believe it was E.T.s arriving on Earth. This plan was eventually abandoned when the studio realised that they could make more money by keeping the two franchises separate and making a Trek film and a Murphy film. In the completed film, Murphy's character was changed to a female marine biologist and played by Catherine Hicks (although many of the scenes written for Murphy's character were used, if slightly altered).
