Who's that Knocking at my Door (1967)

An early movie for both star Harvey Keitel and director Martin Scorsese. We are immersed in a New York Italian borough where J.R. is surrounded by violent young chauvinists and appears to try and break out of this mold by trying to connect with the wild outdoors and by dating an outsider and rather cultured woman. The acting in the film is striking; so much so that we are unsure if the people are real life characters or tremendous actors. There is a particularly tense scene that is a tremendous build up to the shocking conclusion which speaks much of the paternalistic society we still live in today. Parts of the film do drag on and some of the dialogue is muffled, but I think they are essential to understanding the characters.
