Bea Ellen Cameron (credited as B.C. Cameron) was an assistant director on Star Trek: Deep Space Nine.
After filming ended on "What You Leave Behind", Cameron went through a list of the main and recurring cast members of DS9, saying for each "this is good night and goodbye to...". The initials of Biddle Coleridge from "Past Tense, Part I" and "Past Tense, Part II" were a homage to her. (Star Trek: Deep Space Nine Companion, p. 197)
Other shows she has worked on include Knots Landing and Spin City. She also as an assistant director intern on the 1986 film 52 Pick-Up, starring John Glover, Alex Henteloff and Clarence Williams III.
