Must watch Hitchcock Movies

I was not a big Hitchcock fan when I was a teenager and watched his movies for the first time. But now I have can see why his movies are classics. I bet there are hundreds of movies inspired at different levels by his work. I haven't watched all of his movies but I intend to watch them in good time. Here is my list of movies I liked so far , ranked ofcourse.

1. Rear Window
2. North by Northwest
3. Strangers On A Train
4. The Man Who Knew Too Much (1956)
   
5. Psycho (1960)
   

The latest Hitchcock movie that I watched, Strangers On A Train had the most disturbing charectar(Bruno Anthony) I ever came across in a movie and the fact that such a chance encounter with such charectar can happen to any one of us is what makes the movie that much interesting.
