The sixth of sixteen movies with the suave detective nicknamed "The Falcon", and the third of ten starring Tom Conway.
Erford Gage, who plays one of the murderous Morley sons, played Ricky Davis, an entirely different character in the previous Falcon entry, The Falcon Strikes Back (1943). He subsequently appeared in Val Lewton's The Seventh Victim (1943) with Tom Conway before enlisting in the army on August 27, 1943. After rising to the rank of staff sergeant, he was killed in action while liberating the Philippines on March 17, 1945 and is buried there.
This marks the first Falcon film in which he has no sidekick or servant.
Much of the climatic action takes place on RKO's famous Victorian staircase, built for Orson Welles' The Magnificent Ambersons (1942). A year before, star Tom Conway made a fateful climb up it in Val Lewton's Cat People (1942).
