Wait what? Some remade Rear Window?

Why do people keep trying to remake Hitchcock? I guess it's only a matter of time before we get a remake of The Seventh Seal with giant robots.

Even Hitchcock remade Hitchcock.

Many of Sir Alfred's films are better known than the books/stories they are based on.

Robert Bloch wrote a couple sequel novels to Psycho, which have nothing to do with the movies.
