This 1960s film was seen on TV in the early 1970s. It is one of several film versions of the 1960s French play Trap for a Lonely Man.
First of all, the exclusions:
It is not Stranger in the House (1955).
It is not Chase a Crooked Shadow (1958).
It is not Trap for a Solitary Man (1963) (unproduced).
It is not Honeymoon With A Stranger (1969).
It is not One of my Wives is Missing (1976).
It is not Vanishing Act (1986).
A villa in a sunny coastal area, possibly Europe. A woman appears, claiming to be a man’s wife but the man does not know her. The police are called and a detective arrives but when the man gets his wedding picture it is the same woman that is in the photo not his wife. The man’s uncle arrives and there is hushed dialogue as the uncle confirms he has never seen this woman before either. The man is relieved that someone can back his story. But when the detective comes back to the villa the uncle now recognises the woman as being the man’s wife. What the hell is going on? At the end of the movie the man cries out that the woman can’t be his wife…
“Why not?” asks the detective.
“Because… I killed her…” he sobs.
Seen one afternoon in the mid 1970s, probably a film from the 1960s, I believe it was in b&w. There were several film versions of this story but other versions have a priest as a support character rather than the uncle, and some versions have swapped roles so that the man plays the imposter.
This is such a well filmed story I can’t understand why I can’t discover any mention of the particular version that I saw on TV in the seventies. Surely I wasn’t the only person to see it?
