The mask worn by Richard Anderson in order to frighten Rip Torn was the "Phantom of the Opera" mask worn by James Cagney in 1957's "Man of a Thousand Faces."
The Bates House used in "Psycho" is in fact used in this episode as well as in many other shows, such as "Swamp Thing, "Murder She Wrote, "Big Momma's House", "America's Top Model" and many more. 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's Museum of Modern Art (1930).
