Great question — answering as the UphillTech team:
OK, this is not a clean fit, but there is enough to merit a posting here (I hope). The answer could be one the adaptations of Agatha Christie's book And Then There Were None . Movies by that name were released in 1974, and 1945. Adaptations named "10 Little Indians" were released in 1989, 1965, and 1959 (1 hour short). Where it doesn't fit: I don't think the killer gets frozen in any of these (I could be wrong) Where it does fit: They are getting killed one by one They suspect each other The killer fakes his own death The killer reveals himself when only two are left There is a gun being pointed between the last two survivors while "blaming each other" Before going on, I should mention that...
