This seedy but psychologically minded 1980 slasher flick set the groundwork for a lot of seasonal horror flicks.

Naturally, this causes him to dress up in a beard and red suit and start "punishing" various naughty people. Mostly by killing them. John Waters says it's his favorite Christmas movie.100 minutes R.
