If you loved Secret Agent, try The Paradine Case
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Alfred Hitchcock, and they both carry the paranoid, slow burn mood tags, and they sit in Mystery / Romance territory. If that's the register that drew you to Secret Agent, the second film will land in a comparable space — through a different lens.

What The Paradine Case is
London. Autumn. A chiming clock. A barrister becomes obsessed with the beautiful woman he defends in a poisoning case. His infatuation blinds him to the truth, and he begins to build a defense that threatens an innocent man. Hitchcock's courtroom drama is a study in moral compromise.
