The first movie to have its world premiere on a ship: the luxury liner "America", during a trip from San Francisco to Los Angeles.
In 1947, Warner Bros. reissued the film as a double-feature with The Sea Hawk (1940). However, to squeeze more showings per day, the film was cut from 100 minutes to 86 minutes. The edits were made to the original camera negative and the footage was subsequently discarded. A 16mm print that once belonged to John Garfield was in the possession of New York University, but Warner Bros. refused to release the film on DVD until a 35mm print of the longer version could be found. Warner ultimately found a complete 35mm print at the Museum of Modern Art, restored it, and released the film on DVD and Blu-Ray in October 2017.
