The Bates House used in "Psycho" is in fact used in this episode of "Night Gallery" and many shows such as "Murder She Wrote", "Big Momma's House", "America's Top Model" and "Swamp Thing", among others. It actually was modeled after the 1925 painting by Edward Hopper, "The House by the Railroad", which was the first painting ever acquired by New York Museum of Modern Art 1930.
The exterior of the haunted house in "A Question of Fear" is, in fact, the original Norman Bates house facade built for Psycho (1960), which is located (and can still be seen on tours) at Universal Studios in California.
Helmut Dantine - cast as a Nazi for this show - played similar characters during the 1940s for Warner Bros.
