You’re wonderfully sly and wicked in your role! Johnny O'Clock seems to have everything sorted out. He owns a share of a successful casino, and his minor flaws are easily accommodated within his world. However, things begin to unravel; his partnership with the Marchettis family faces difficulties because of Mrs. Marchetti’s affairs, and to make matters worse, the hat check girl he was fond of is found dead. Johnny finds himself under pressure from all sides. As of now, Johnny O' Clock has fewer than ten reviews on IMDb and just around 200 votes, suggesting it hasn't been widely seen. Without knowing about distribution problems on TV and DVD, it’s possible this small noir film has simply been overlooked by many genre fans. It doesn't try to reinvent noir or its related styles; instead, it includes all the essential elements of the genre—a skillfully made film that certainly deserves a larger audience. The story, though simple for the kind of movie it is (which makes it accessible even for casual viewers), involves layers of deception and intrigue, flavored with an alluring female character. Add in corrupt police officers, and have Robert Rossen direct his first feature, along with Burnett Guffey’s cinematography, and you get a satisfying noir experience. All that's needed is for the actors to deliver, and fortunately, they do. Dick Powell portrays Johnny O'Clock with an appropriate mix of stylish charm and understated strength, while Lee J Cobb (the tough police officer), Thomas Gomez (Pete Marchetti), and John Kellogg (the enforcer) all play their parts convincingly without going overboard. The female characters are well-cast with Evelyn Keyes ("99 River Street" & "The Seven Year Itch"), Ellen Drew ("The Man from Colorado") and the captivating Nina Foch ("The Ten Commandments")—with Drew occasionally resembling a young Rita Hayworth, though only briefly. It's not an intensely dark film, so those seeking something complex will be let down, and I’d be lying if I said that I didn’t think the conclusion could have been more impactful. But I must say it was quite enjoyable; "Johnny O'clock" is twisty and engaging without being overly confusing, and it's well worth watching. Time! Get it? Sigh. 7/10
