(written from a Production point of view)
Brooke Breton was the Associate Producer of Star Trek IV: The Voyage Home, Star Trek V: The Final Frontier, and Star Trek VI: The Undiscovered Country. She was also the Post-Production Supervisor on Star Trek: The Next Generation during its first season.
Breton is currently a visual effects producer and supervisor at 20th Century Fox. Among the films she has worked on for the studio are True Lies (1994), Solaris (2002), and Master and Commander: The Far Side of the World (2003). For the latter project, Fox brought Breton in when it was found that more visual effects would be needed, and Breton called on Industrial Light & Magic for help.  She went on to receive a nomination from the Visual Effects Society (VES) Award for Outstanding Supporting Visual Effects in a Motion Picture for her work on Master and Commander, which she shared with Star Trek matte artist Robert Stromberg and two others.
Besides producing visual effects, Breton has made occasional returns as a film producer. She produced DreamWorks' animated film, The Road to El Dorado, and is credited as a Co-Producer on Paramount Pictures' Sky Captain and the World of Tomorrow. According the The Hollywood Reporter, she was also an effects producer on Sky Captain. The Reporter also stated that Breton was "a strong candidate" to take over the previsualization system developed by Robert Legato for use on an upcoming film for director James Cameron. It appears she won the honor since Breton is currently supervising the visual effects for Cameron's Avatar, a film starring Zoë Saldana and due for release in 2009.
