15Terry Farrell - Star Trek: Deep Space Nine
Terry Farrell played the role of Jadzia Dax in the first six seasons of Star Trek: Deep Space Nine. Jadzia was killed off at the end of Season Six, with the Dax symbiont moved to another host.
The reason Jadzia was killed off was due to Terry Farrell wanting to leave the show.
She had been offered a role in Becker, where she wouldn't have to endure extended periods of time in the makeup chair every day.
Farrell has also revealed that she hated working with Rick Berman, which was the final straw in causing her to leave.
The final episode of Star Trek: Deep Space Nine includes a scene where all of the characters have flashbacks of their time aboard the station.
The producers had wanted Terry Farrell to return for a new flashback sequence, but it had to be scrapped, as they couldn't meet her salary demands. She also refused to give them permission to use footage of her during any of the other flashbacks.
