The picture was directed by Stuart Heisler starring Brian Donlevy, Veronica Lake and Alan Ladd (who plays the actual lead despite being billed third). A successful earlier film version starring George Raft in Ladd's role had been released in 1935. The 1942 version's supporting cast features William Bendix, Bonita Granville, Richard Denning and Joseph Calleia. Source: Wikipedia (en)
