I saw this movie once as a child and it has always escaped me . For a long time i thought i just imagined it , that it never existed , then i saw it again some 20 years later . Its not a great film by any means but i think it attains classic status solely on the dialogue and filming techniques . I mean how can you not like a grainy black and white film with poor lighting and extreme closeups with dialogue like ."Ive called you all here because the killer is amongst you, here in this room " " the killer is...." then the light goes out and there is a shot ... and then ... well you will have to see this movie to find out how it ends.. its a classic.. If any one has seen ths recently please let me know...I will be forever in your debt....
