No, it doesn't feature all of his great films, but the films it does include here easily make this set worth 5 stars.
The Birds, Vertigo, Psycho, Marnie, Rear Window and The Man Who Knew Too Much are all classics. They're all amazing 5 star classic Hitchcock.
Other great films in the set, Frenzy (his first in Britain for over 30 years), Shadow of a Doubt (often said to be Hitch's personal favourite of his films), Saboteur and Rope.
This, along with the other boxset on Play, and you have most of his films from the 1940s onwards.
