Upon re-watching Alfred Hitchcock's popular and scary 1960 mega-hit, "Psycho", recently (plus the plentiful and pleasing extra features on the Universal DVD) it struck me at how awful [from a "spoiler" standpoint] Hitchcock's very own self-hosted Theatrical Trailer was for this film. Or ... Is it possible that Hitch's "Tour of the Psycho set" Trailer was, in fact, NOT the "Original" trailer utilized prior to the film's first release in June 1960? Could this "Tour" trailer (which gives away, IMO, way too much info) possibly have been put out for the "Re-release" of the film a year or two after its 1960 debut? And, if yes, I wonder what the "Original" Trailer from early to mid 1960 was like. (If there was one.) For anyone who has never seen Psycho previously (of which there are few I realize), I would certainly NOT recommend viewing the DVD's Trailer before watching the film. There's not a single scene from "Psycho" used in the 10-minute Trailer, but ..... The Trailer tells the viewer (unsuspecting of plot points or otherwise) right off that we're going to see at least two brutal killings -- and WHERE we'll see them! One in the shower and one on the staircase. I often wondered WHY Hitch wanted to reveal this much data regarding his film, which was shrouded in secrecy at the time. ("No one, but no one, will be admitted to the theater after the start of each performance of Psycho!") What other trailers on current DVD products give away too much of the plot do you think?
