I've always been fascinated by the fact that Psycho 2 was released 22 years after the original. Starring the original Norman, Anthony Perkins. All the while being a dam good movie.
Not bad at the box office to boot. Made for around 5 million, pulled in close to 35 million. And that was 1983. One of the best horror movies to come out that year along side of Christine & Cujo. Only horror movie that did better (money wise)was Jaws 3 in 3-D. And people were in for a surprise with that fair/poor entry to the Jaws series.
Teaser trailer: (that's the late great Percy Rodriguez voice over)
And remember, there wasn't any internet, you found out (for the most part) the first time about new future movies from trailers in the theaters. How great was it to see this little teaser for the first time.
