Better than The 39 Steps, this movie at least has an interesting turn in the middle. Instead of plot contrivances it actually takes a meta-commentary on films with plot contrivances and bakes it into the plot. Peter Lorre is marvelous here, as always, and the cast has chemistry and is well-suited to their individual roles. Unfortunately the ending leaves quite a bit to be desired, opting for more of a ‘that’s all, folks’ wrap-up than a more satisfying ‘Hitchcockian’ twist. Still, it’s good film-making overall and a fun older movie.

Closest comparison: It’s a more interesting 39 Steps
