Query: thrilling dark long 70's horror suspence at is best.

Donald sutherland finest horror performance you must discover. Might be long sometime cause of is foreign situation in Venice. If you liked sutherland in (invasion of the body snatchers, 1978) you'll love that one too. It's a rare horror thriller that people of this generation forgot about. One of the must shocking ending i ever saw in a horror suspence movie with a cool old thrilling music.
