You've all watched Hitchcock's Mr. & Mrs. Smith, and listened to the radio presentation I posted here a bit back. I recently found three more presentations of the story:
Gulf Screen Guild Theater - February 8, 1942 (10 MB - MP3)
Errol Flynn and Lana Turner
The Lady Astor Screen Guild Theater - December 14, 1942 (14 MB - MP3)
Robert Young, Joan Bennett, and Ralph Bellamy
The Lady Astor Screen Guild Theater - January 2, 1945 (13.5 MB - MP3)
Preston Foster and Louise Allbritton
All three offer the same version of the Screen Guild Theater script, just with different players. Two of the three presentations offer a celebrity voice, which I will not mention here, but is fall-off-the-chair funny when you hear him.
I'm partial to the Robert Young version, for obvious reasons, plus Ralph Bellamy as Jeff Custer is a perfect match. Errol Flynn as David...nope, doesn't cut it.
You may not want to listen to all three in one sitting - you'll end up with odd dreams of David (or Ann).
