"Crossfire" is remembered not so much for the fact that its three stars all had the first name "Robert" but as being one of the first Hollywood films to deal with anti-semitism.
The story opens with the murder in silhouette of a man whom we later learn is a Jewish man named Joseph Samuels (Sam Levene). Pipe smoking police Captain Finlay (Robert Young) is assigned to the case. An ex-soldier, Montgomery (Robert Ryan) comes upon the murder scene and we learn through flashback that he had met Samuels in a bar along with other soldiers who were in the process of being mustered out of the service following WWII.
According to Montgomery, he and pal Floyd Bowers (Steve Brodie) had followed Samuels and Cpl. Arthur Mitchell (George Cooper) to Samuels' apartment for drinks. Montgomery tells Finlay that Mitchell left the apartment first and that he and Floyd followed soon after with Samuels still alive and well.
Unable to locate Mitchell, Finlay suspects him of the murder. He enlists Sgt. Peter Keeley (Robert Mitchum) to help him locate Mitchell. Mitchell meanwhile has been wondering the streets in a dazed state. He meets prostitute Ginny (Gloria Grahame) in a bar and strikes up a friendship. She gives him a key to her apartment and he goes there to rest. Unexpectedly a man (Paul Kelly) turns up looking for Ginny. Mitchell, still in a daze, leaves and goes back to meet Keeley and his pals. Keeley manages to keep him from the police and hides him in an all night movie house.
From Mitchell's perspective we learn that Montgomery hates jews and is probably the killer. Finlay begins to focus his investigation on Montgomery trying to prove his guilt. He arrangers to have one of the soldiers, a kid named Leroy (William Phipps) set a trap for Mongomery.
"Crossfire" is considered to be one of the best of the "film noire" genre. In fact it garnered several Academy Award nominations including Ryan and Grahame for best supporting actors. It was made on a modest budget in about three weeks.
It has all of the elements of classic "film noire", the shadows, low key lighting and the story playing out mostly at night. The requisite "femme fatale" of the piece is Grahame's Ginny who plays a minor role but is nonetheless your classic "femme fatale". The unnamed character played by Paul Kelly (in an excellent bit) has been chewed up and spit out by Ginny and was she about to do the same to Mitchell?
Robert Ryan steals the picture as the brutal Montgomery although it would type cast him in similar roles for years to come. Robert Young makes a good low key detective but Robert Mitchum has little to do other than befriend the Mitchell character. Others in the cast are Jacqueline White as Mitchell's wife, Lex Barker (who would go on the following year to play "Tarzan") as one of Mitchum's soldier pals and Richard Powers (who was previously known as Tom Keene) as Finlay's assistant.
Director Edward Dmytryk would shortly run afoul of The House Un-American Committee as having communist affiliations and spend a couple of years in jail.
