This film was not intended to stand by itself, but was designed as the cinematic aspect of Welles' Mercury Theatre stage presentation of William Gillette's 1894 comedy about a New York playboy who flees from the violent husband of his mistress and borrows the identity of a plantation owner in Cuba who is expecting the arrival of a mail order bride. The film component of the performance was ultimately never screened due to the absence of projection facilities at the venue. Long-believed to be lost, a workprint was discovered in 2008 and the film had its premiere in 2013.
