THE BLACK CURTAIN

Cornell Woolrich's 1941 novel The Black Curtain was performed three times over the years on CBS Radio, twice as a half-hour program and once as an hour program.  The radio versions more closely resembled Street of Chance, the 1942 adaptation of the novel, rather than the original book.  Nonetheless, Francis Nevins felt that this radio adaptation captured the essence of Woolrich and actually improved the novel's ending:  "(T)his play...was at once so different from the source material and too true to its dark spirit that I'm almost convinced it was adapted by Woolrich himself..."

From November 30, 1944, here's Cary Grant as the amnesiac Frank Townsend.  Lurene Tuttle, who appeared on the radio as Sam Spade's secretary and in such films as Don't Bother to Knock, Niagara, and Psycho, co-starred as Ruth.

Enjoy.
