16 Star Trek Actors Who Died In 2025

Born Roy Baker in Tulsa, Oklahoma, in 1935, Rex Holman appeared twice in Star Trek. First, he played the illusory form of Morgan Earp in Spectre Of The Gun, then returned as J'onn in Star Trek V: The Final Frontier.

Before his turn to screen acting, Holman did a lot of work in theatre, gradually moving from smaller venues up to larger theatre halls. He got his start in Hollywood alongside film crews, eventually finding his niche in cowboy Westerns. He often found himself playing villainous roles.

In The Final Frontier, he appears as Sybok's right-hand man, J'onn, though this appears to be either his last, or among his last, roles on screen. Though he appeared in many of the major TV shows of the '60s, Holman credited his theatre work as a way to "rid" himself "of complexes."
