Actress, producer and development executive Karen Montgomery died Dec. 4 in Los Angeles following a nearly decade-long battle with breast cancer. She was 66.

Montgomery started in showbiz as an actress, starring most notably as Princess Beata in a 1988 episode of “Star Trek: The Next Generation.” She then moved behind-the-scenes role, working as an assistant to screenwriter Waldo Salt, director Hal Ashby and producer Bruce Gilbert on 1978’s “Coming Home.”

Throughout her career she worked in the development departments of indie film companies, with producing credits on films including “Row Your Boat” (1999), “‘Til There Was You” (1997) and “Diary of a Hitman” (1991), which was directed by Montgomery’s former acting coach and friend Roy London.

Following London’s death from AIDS complications in 1993, Montgomery and husband, director Christopher Monger, produced a documentary called “Special Thanks to Roy London,” which premiered at the Tribeca Film Festival in 2005.

Montgomery is survived by her husband; her mother Susan Nelson; and brother Carl Montgomery.
