Roman Polanski made some films in Poland before moving to the U.S. (and later France). Knife in the Water was, I believe, his only feature there, and it’s obvious why he quickly moved on to bigger productions. Knife in the Water is a classic thriller in the vein of Hitchcock and Chabrol. Criterion put out a great DVD a while back, and also included a selection of Polanski’s short films. 3.5/5
