And Then There Were None (1945), directed by René Clair, is one of several film adaptations of Agatha Christie's best-selling mystery novel And Then There Were None concerning several people summoned to an island retreat by a mysterious stranger, only to meet their ends one by one.

The film changes certain characters' names and adheres to the ending of the play rather than that of the novel. Though its subject matter is dark, the film is humorous in places. It was directed by Rene Clair from a screenplay by Dudley Nichols. Its cast featured Barry Fitzgerald, Walter Huston, Louis Hayward, Roland Young, June Duprez, Mischa Auer, C. Aubrey Smith, Judith Anderson, Richard Haydn and Queenie Leonard as the people stranded on the island. The film could arguably be seen as a precursor to the modern slasher film.

Though it was produced by a major studio, 20th Century Fox, the copyright to the film was allowed to lapse and it has now fallen into the public domain. As a result several different editions are available of varying quality.

And Then There Were None is a 1974 film version of the Agatha Christie mystery novel of the same name. It follows the script of the 1965 version, though this particular adaptation is set in an abandoned hotel in the Iranian desert; the film was shot in the Shah Abbas Hotel in Iran during its pre-revolution days. The film's run time is an hour and thirty-eight minutes and it is the first film version of the novel to be filmed in color.

This version is generally loathed by the fans of the book due its nearly incomprehensible changes to the plot, the characters and is notable for some truly bizarre miscasting, despite generally positive reaction to Charles Aznavour's performance. The film is considered one of the worst adaptations of Agatha Christie's works.

Ten people are invited for a weekend on an island by a Mr U. N. Own, but he isn't on the island. At dinner a record is played, by that all the people are accused of murder, suddenly the first of them is dead, then the next... It seems to be that one of them is the murderer Mr. U. N. Own, but the person in suspect is always the person who is murdered next. At last only two people seem to be left. Written by Stephan Eichenberg
