Sequels and remake

Three sequels were produced after Hitchcock died: Psycho II (1983), Psycho III (1986), and Psycho IV: The Beginning (1990), the last being a part-prequel television movie written by the original screenplay author, Joseph Stefano. Anthony Perkins returned to his role of Norman Bates in all three sequels, and also directed the third film. The voice of Norman Bates' mother was maintained by noted radio actress Virginia Gregg with the exception of Psycho IV, where the role was played by Olivia Hussey. Vera Miles also reprised her role of Lila Crane in Psycho II. The sequels received mixed reviews and were universally considered inferior to the original.

In 1998, Gus Van Sant made a nearly shot-for-shot remake (in color) starring Vince Vaughn, Julianne Moore, and Anne Heche. Van Sant said that his film was "a huge kind of experimental project", and that, though it did not do well commercially or critically, he may do it again, with more changes.
