Who's That Knocking At My Door is primarily of historical interest, more an exercise in style - in this case a New York 60s spin on nouvelle vague and Italian neo-realism - than a work of substance. Expanded from a film school project, Scorsese's feature debut is typically light on plot, counterpointing Harvey Keitel's Mean Streets-lite time-wasting with the boys from the old neighbourhood with his failed romance with Zina Bethune that offers the possibility something better. There's more energy than insight and the passage of time has dulled it's edge, but it's not without interest, especially in the way that at times Keitel seems to be playing Scorsese, never more so than in the scene where he picks up Bethune by talking about The Searchers after seeing a picture of the Duke in her copy of Cahiers du Cinema.
