This film marked George Sanders' last appearance as Gay Lawrence, "the Falcon." According to a pre-production news item in Hollywood Reporter, Sanders, who was on loan from Twentieth Century-Fox, wanted out of the series after completing his four-picture commitment to RKO. Although the RKO asked Sanders to continue, he preferred to work on "A" productions. To carry on the series, Tom Conway, who was Sanders' real-life brother, was introduced in this film as Gay's brother Tom. This picture also marked the first associate producer assignment for former writer Maurice Geraghty. For further information about the series, consult the Series Index and for The Gay Falcon.
