Weirdly, the month of December has sort of become my ideal month to just tackle a bunch of film commentaries.
Perfect time to get cozy, get a little high, and listen to director's indulge themselves or an excellent film critic really tackle a film.
The commentary that first opened my eyes and the one I love to recommend is Howard Suber's 1987 commentary of The Graduate (1967). Opened my mind on how truly groundbreaking that movie is.
