Ten Little Indians (1974)

A lush Agatha Christie adaptation. A group of strangers are mysteriously assembled to a remote hotel in the Iranian desert by U.N. Owen (Orson Welles), the strangers who include Charles Aznavour (who of course gives us a song), Richard Attenborough, Herbert Lom, Adolfo Celi and Oliver Reed - all discover they have been bought together under false pretenses by U.N. Owen (or Unknown).

Then a tape is played where Owen's voice rings out, he tells them all they have gotten away with murder. Then the guests begin dying one by one. Who is the murderer? Is it one of the guests? Will any of them survive?

Although not the best version of this story, a bit slow at times, the sheer amount of star power and the surroundings especially the Persian architecture makes this film highly watchable and enjoyable. It is dark and suspenseful as such a situation should be.
