Considered an unofficial sequel to the previous year's box-office success La falaise mystérieuse (1944); both are mystery stories that share actress Gail Russell, director Lewis Allen and several other crew members, but are otherwise unrelated in story or characters. The film posters compared the two films and proclaimed: "More Exciting Than The Uninvited" and "Menace More Deadly Than The Uninvited!"
When Mr. Fielding, meets Miss Howard, he is disappointed she is not as old as twenty five. In fact, Gail Russell, who played her, was no older than twenty when she made this film, and Joel McCrea, who portrays Fielding, was about forty. Unfortunately the beautiful Gail Russell died just over fifteen years after making this, aged only thirty six, due to severe alcoholism. Ironically, in the film, her character does not drink. McCrea outlived her by twenty nine years, dying aged 84 in October 1990.
The Ethel Lina White novel on which this film was based, Midnight House (U.S. title: Her Heart in Her Throat), was first published in 1941.
Final film of Phyllis Brooks.
