In 1974, film archivists Robert Gitt and Anthony Slide retrieved several boxes of photographs, sketches, memos, and letters relating to the film from Laughton's widow Elsa Lanchester for the American Film Institute. Lanchester also gave the Institute over 80,000 feet of rushes and outtakes from the filming. In 1981, this material was sent to the UCLA Film and Television Archive where, for the next 20 years, they were edited into a two-and-half hour documentary that premiered in 2002, at UCLA's Festival of Preservation.
