Alfred Hitchcock's Frenzy (1973)

I saw this at the university when I was in high school and thought the opening titles were a little sedate for a Hitchcock movie. It was a long helicopter shot of London, a little like the opening shot of the model town in The Lady Vanishes. 

Hitchcock's second-to-last film. After a period of decline in the '60's, this was his vindication. Hitchcock for the '70's, a murder movie with a man falsely accused, circumstances conspiring to make him look really, really guilty. There were no obvious process shots. And there was nudity, although, horribly, it was mostly women who were dead or being murdered.

 

As he told Truffaut, his cameos in his movies had become a burden. Hitchcock had to get it out of the way quickly so the audience would quit looking for him and just watch the movie. He's easy to spot in the opening crowd scene. 

 

There's a necktie killer loose in London. As in his other movies, there are no unnecessary scenes. Everything contributes to the plot. And it gets moving very quickly.
