This fine classic combines a great director, a great story, and a great cast. Any one of those would have made for a good movie, but all three make it an excellent one. Hitchcock's style and eye for detail combine very well with a story (from a novel that is extremely good in its own right) filled with psychological fear and settings that are interesting and suggestive.
Most of the time the story itself moves fairly slowly, allowing the focus to be on the characters, but there are also a couple of very good plot twists, which can be very surprising if you've not seen the movie or read the novel. So if you happen not to know the story, it's a good idea to see the film before reading a lot of comments about it. Laurence Olivier, Joan Fontaine, Judith Anderson, and George Sanders are all perfectly cast and do a wonderful job bringing their characters to life, and making you feel a part of the story.
"Rebecca" should be satisfying not only to any Hitchcock fan, but to anyone who likes classic movies. Whether you like romance, suspense, or drama, they're all here, and put together by a director and cast that are masters of their art.
