Strangers on a Train*
A great thriller and undoubtedly, one of Hitchcock's better works, no doubt.
He wonderfully illustrates how the unsuspecting Guy Haines is lured into Bruno's trap. Not even in a naive way, he is just trying to be polite to a clingy fan. It also sets up how he has no space to move. The drunk professor was a nice touch in that aspect.
The actors shine in their parts. Robert Walker as the insane Bruno. Farley as Guy, who goes from a charming, polite young man to somebody driven to madness. And Patricia Hitchcock as the bubbly sister Barbara. She adds a bit of relief and a lighter touch to the procedings.
