Time After Time is a 1979 American science fiction film written and directed by Nicholas Meyer and starring Malcolm McDowell, David Warner, and Mary Steenburgen. Filmed in Panavision, it was the directing debut of Meyer, whose screenplay is based on the premise from Karl Alexander's novel Time After Time (which was unfinished at the time) and a story by Alexander and Steve Hayes. The film presents a story in which British author H. G. Wells uses his time machine to pursue Jack the Ripper into the 20th century.
