Knife in the Water (1962)
Apparently this was Polanski's only film that was made in Poland, which is pretty cool. Best parts of this movie were the music he used and the shots he got on the lake, which were pretty cool. I can't say I have much of a shit about the characters or the plot, really, I just enjoyed the style of the film and liked the ending. Solid movie but not one of Polanski's best, from what I've seen.
