Two legendary movie stars make the most of the situation in this enjoyable, if not exactly that believable, drama. Anthony Perkins is Laurence Jefferies, a neurosurgeon working in Britain who intends to do something about his cheating wife Frances (Jill Ireland, a.k.a. Mrs. Charles Bronson). He realizes that an amnesiac (Bronson) whom he's just met will make the perfect patsy. All he has to do is convince the stranger that Frances is *his* wife, lay out evidence of the affair, and let the stranger get revenge on behalf of him.
The script (adapted from a novel by Jacques Robert) may not exactly be airtight, but the set-up is still pretty irresistible. Director Nicolas Gessner ("The Little Girl Who Lived Down the Lane") handles things in capable if not overly stylish fashion. Part of the effectiveness stems from enjoying the machinations of this doctor, and how he's spent so much time working on solving his problem. True enough that he may be tops in his field, but as we can see, he's been a highly inadequate husband. Perkins is so much fun to watch in this antagonistic role.
But any fan of Bronson will find this particularly compelling since Bronson is not a macho man of action, but a highly suggestible and vulnerable character (who doesn't even receive a proper name). Ireland delivers one of her better performances as the wife; good support is provided by Henri Garcin as the lover, Adriano Magistretti as Jefferies' brother-in-law, Agathe Natanson as Lucy, and Colin Mann as the police sergeant.
The conclusion to the film may come as disappointing to some viewers, since very little is resolved, but others may find it intriguing that the film ends with a question mark. (All those cuts, back and forth, between two of the main characters get annoying quickly, however.)
Thankfully, "Someone Behind the Door" is over and done in a reasonable amount of time, so at least it doesn't go on longer than it really should.
Seven out of 10.
