I’m looking for a film in which there is the following scene: A man and a woman are about to visit a man. The woman is skeptical. The man offers her that they make a sign that the woman should give him if she wants to leave. The sign is a pulling on the ear. The man they then visit shoots an arrow vertically into the air, after which the arrow falls back down on them. The woman then pulls on her ear to signal to her companion that she wants to leave now.
That is Garden State (2004)
starring (and directed by) Zach Braff as the man
and Natalie Portman as the awkward girl friend.
