Wait Until Dark (1967) - Now I've Got The Proof!

Acting flourish for Alan Arkin, though we don't know the frantic intruder is his character in disguise, meeting young Gloria (Julie Herrod), then blind Susie (Audrey Hepburn), the mark in the con, who is rescued by new friend "Mike" (Richard Crenna), and cop Jack Weston, whom she doesn't know are both also crooks, in Wait Until Dark, 1967.
