Spion im Orientexpress

Background to Danger is a 1943 World War II spy film starring George Raft and featuring Brenda Marshall, Sydney Greenstreet, and Peter Lorre.

Based on the 1937 novel Uncommon Danger by Eric Ambler and set in politically neutral Turkey, the screenplay was credited to W. R. Burnett, although William Faulkner and Daniel Fuchs[2] also contributed. The movie was directed by Raoul Walsh.

The film was designed to capitalize on the runaway success of Casablanca, which had also featured Lorre and Greenstreet. The Russian operative positively portrayed by Brenda Marshall shows an exaggerated degree of cooperation,[3] and the film has a slight pro-Soviet bias akin to Warners' Mission to Moscow from the same year.

Walsh called the film "a quickie".[4]
