"Time After Time" (1979)

BACKSTORY: A 1979 American science fiction film starring Malcolm McDowell, David Warner, and Mary Steenburgen. It was the directing debut of screenwriter Nicholas Meyer, whose screenplay is based largely on the uncredited novel of the same name by Karl Alexander (which was unfinished during the time the film was made) and a story by the latter and Steve Hayes. It tells about British author H. G. Wells and his fictional use of a time machine to pursue Jack the Ripper into 20th century San Francisco.
