This movie is a typical Hitchcockian thriller mixed with an era romantic comedy. Unfortunately, the romantic parts of the plot are fundamentally at odds with the thriller parts, and the tone ends up trying to be endearing where the plot necessitates tension. The central ‘cellar key’ scene is fantastic and if the entire film was like that it would easily be at least a 4/5 film, but it ultimately can’t overcome its own contradictions.

Closest comparison: It’s like Roman Holiday (1953) by way of Secret Agent (1936).

Setting: Espionage
Plot: Thriller
Tone: RomCom
