Bill Paxton and Glenne Headly, who played the parents of Mae, would both pass away the year of the film's release. Paxton died two months prior to the film's release on February 25 due to complications from heart surgery, and Headly died of a pulmonary embolism less than two months after the film's release on June 8.
