Sam Jackson’s Secret Video Diary is a British independent film. The makers believe it is notable for being the first film ever made whose leading actor has died before the start of principal photography.[1] The film’s eponymous lead was played by Posy Miller, who died of acute leukemia on 24 December 2002.
The film takes the form of a TV documentary, and tells the story of a missing person, Samantha Jackson. One of Sam’s friends discovers fragments of a video diary she had been making as a secret reality TV project, and comes into contact with the producer who has also lost touch with Sam. As the months go by, more tapes come to light, providing clues as to what really happened to Sam Jackson.
