Eddie Murphy was originally supposed to have starred in "
Star Trek 4: The Voyage Home", instead of Catherine Hicks. Murphy was supposed to be a professor concerned with UFO's who spots the de-cloaking Klingon ship at the Super Bowl. Apparently, everyone else was to be convinced the ship is a half-time special effect while Murphy believed it was real. Paramount declined this script for two reasons: firstly, they didn't want to combine their two most profitable franchises ("Star Trek" and "
Beverly Hills Cop"), and whilst deciding on their plans, Murphy had signed on to do "
The Golden Child" instead.
