Although the theme of "The Wrong Man" could apply to several of Hitchcock's more famous thrillers, this movie is unique in holding closely to a series of events as they actually happened. That means there is a lot less of some of the usual Hitchcock features, such as his famous set pieces or his subtle humor. They are replaced by a different kind of suspense, still done with Hitchcock's usual craftsmanship.
Henry Fonda and Vera Miles play a factual ordinary couple whose lives are thrown into turmoil when the police confuse the husband with a man who has been committing a series of robberies. The first part of the movie concentrates on the nightmare he undergoes in being interrogated, jailed, and arraigned. Fonda's convincing acting, along with Hitchcock's detail-oriented filming, enable the viewer to feel the anxiety and helplessness of an innocent man being horribly misjudged. In the second part of the movie, as Fonda gets ready to go to trial, the ordeal finally starts to take its toll on his wife.
Although this has to be ranked as a minor work compared to Hitchcock's long list of masterpieces, it is a worthwhile film in its own right, as long as you have the right expectations in watching it. It can be quite uncomfortable to watch these things happen when you know that it all really occurred, and Hitchcock uses his skill to help us see just what an ordeal it was.
