Ten Little Indians

There are many versions of this Agatha Christie story, often known as And Then There Were None. This one is an hour-long teleplay for British television, starring Nina Foch, black and white, from 1959. The show also features Barry Jones, Romney Brent, Valerie French, and James Berwick.

The setting for this particular adaptation is a mansion in the Alps.

Certainly not the best version, though, since it's only an hour, people drop like flies fairly quickly. The version I saw was a lousy print.

For reasons known only to whomever advertised this film on streaming, one is given to believe Hugh O'Brian is in this. He is in a later version.
