Who's That Knocking at My Door (1967)

Martin Scorsese's powerful drama shot in gritty black and white on the streets of the Italian-American communities where he grew up, stars Harvey Keitel as JR, a young New Yorker who falls in love with an independent and free-spirited college graduate (Zina Bethune). However, he finds his values shaken when she reveals secrets about her past. Hailed by Robert Ebert on its original release as 'a great moment in American movies', Martin Scorsese's debut feature film introduces many of the themes and techniques that he would later revisit in his classics Mean Streets, Taxi Driver and Goodfellas.
