It all began when Gene Roddenberry convinced Desilu to foot the bill for not one, but two "Star Trek" pilots; thanks to Desilu's boss, America's darling Lucille Ball, the world met Kirk, Spock and McCoy.

Paramount wanted to launch a fourth network with the new Star Trek series Phase II as its flagship. When the network proved unworkable, Phase II appeared doomed - until Star Wars and Close Encounters of the Third Kind proved box office hits. Phase II became the 1979 blockbuster Star Trek: The Motion Picture.

In 1987 Paramount decided Trek should return to its roots: television. ST: The Next Generation would become the first hour-long scripted show sold directly to the syndicated television market. Paramount's gamble paid off. Who hasn't heard of Picard, Data, and Worf?

1995 brought another Trek series. This one featured a new starship, a return to episodic storytelling, and Trek's first female Captain, Kathryn Janeway. It was also the flagship for Paramount's new television network, United Paramount Network (UPN). Despite running seven seasons, the addition of Seven of Nine wasn't well-received by the entire cast.

From the series regulars and recurring roles down to the folks who just did guest spots, thousands of actors have brought the characters of Star Trek to life. Hear them tell what it's like on their side of the camera lens.
