This is one of RKO's first films. It's also the only pairing of all three Moore brothers. It also features nightclub dancer George Raft in one of his first attempts to break into films (after this he didn't appear again until 1931 when he was "discovered.") Sadly, this film is all curiosity value and nothing else. The Moore brothers are mostly terrible (Owen, playing the gangster, being the only one with any talent for handling dialogue). Raft is actually better and livelier than the Moore boys even though his part is slim. There is also no music score whatsoever, outside of the nightclub sequence with Raft, thus what little dramatic force the film has is left dry by the silent soundtrack. The story is the typical brothers-gone-separate-ways stuff (one is a cop involved in murder case that leads to other brother who is gangster) with the only difference being that there is a third brother (a doctor) in the middle. But the Doctor's part isn't very interesting, so it doesn't distract from the clichés, unfortunately. Sound killed the Moore brothers' careers and this film easily shows us why.
