Sorry, Wrong Number (AKA Prominte, omyl - 1963)
http://www.imdb.com/title/tt0176055/
A Czech TV adaptation of the Lucille Fletcher play starring a great Czech actress,
Jirina Sejbalova. It runs for 30 minutes and it's basically word-to-word the original play. IMO it works even better than the film with Barbara Stanwyck (which I love). Sejbalova delivers a masterful performance, starting with a very subtle and quiet woman (unlike Moorehead and Stanwyck in their versions) and gradually growing more and more hysterical. There is no music except for the opening credits, which makes it even more scary.
If anyone is interested in seeing it, I'll try to find a way how to rip it from the VHS, subtitle it and post it on youtube.
