Movie Trivia #018: Tied to Be Fit

Sam Waterston can't keep up with his tie in a scene from Woody Allen's September (1987). The movie has much to do with the expression of angst during a weekend in Vermont (has there ever been a Woody Allen movie sans angst?). Waterston's is so severe that during a conversation with Jack Warden, his necktie is alternately tied and untied at regular intervals.

I don't know. This sounds more like an artistic intent rather than a contingency error, but then again I'm not a film major.
