The film was directed by George Sidney who says that George Seitz meant to direct the film but dropped out at the last minute. Sidney directed a screen test for Lee Bowman. He used Jean Rogers to appear alongside him and MGM executives liked the test so much that both were cast in the film. The film was shot in 22 days although Sidney was unhappy he had so little preparation time.
According to MGM records the film earned $253,000 in the US and Canada and $154,000 elsewhere, making the studio a profit of $23,000.
