Marina Sirtis
Lt. Deanna Troi on the syndicated sci-fi smash, "Star Trek: The Next Generation" (1987-94), Sirtis began playing small roles in both British and American features and TV, typically as seductive types ranging from the "girl in Porsche" in "Space Riders" (1983) to a prostitute in "Blind Date" (1984). She gave a powerful portrayal on "Star Trek," tackling her character's problems with her family, her semi-telepathic powers, her career ambitions and her hinted-at romantic involvements with fellow Enterprise officers Riker and Worf. Sirtis went on to reprise her signature role in the "Star Trek" features and several episodes of the spin-off series "Star Trek: Voyager," as well as TV sci-fi fare such as "Stargate SG-1" and "Gene Roddenberry's Earth: Final Conflict."
