ObscureHollywood.net’s review published on Letterboxd :
Leslie Banks has obtained information that a group of anarchists, led by Peter Lorre, do not want him to disclose. To stop Banks from talking, the anarchists kidnap his daughter, Nova Pilbean. Banks sets out to save his child and thwart the conspirators plans to assassinate a visiting diplomat.
This early film from Alfred Hitchcock, although slow and overly talkie in parts, is very enjoyable. Lorre and Banks exchange some amusing dialogue before the situation becomes too tense for levity. The film closes with a big shootout that produces a slam-bang ending. It was Peter Lorre’s first English-language film; he learned much of his dialogue phonetically.
Hitchcock remade the film in 1956 with James Stewart and Doris Day.
