The New York Times doesn't like it. Films de France says, "Secret Agent is an entertaining example of its genre, shot through with occasional moments of artistic brilliance," while noting "Peter Lorre’s comical over-acting". Salon.com calls it "freakish" and "fascinating" and "the weirdest movie Hitchcock made". The Spinning Image calls it "a real curiosity" and says,
