In Annie Proulx’s original short story, Jack mentions a dark incident in Sioux Falls where he was picked up by a man and subsequently beaten. This is largely absent from the film, aside from the tragic implication of his death.

The absence of deleted scenes for Brokeback Mountain is not an oversight but a testament to its tight construction. By denying viewers "extra" time with Jack and Ennis, the film forces the audience to feel the same sense of loss and "what could have been" that Ennis feels at the end of his life.
