Really? Were they Montana kids? Actually I don't even know anymore where they filmed that movie, now that I think about it..
At any rate the girl is probably lucky she didn't end up with Randy Quaid, as he sort of went off the deep end..
He went to school in Darby and also Dillon and I think they filmed around Billings. They would have been out of high school by then so she had probably moved away from home and she told him they picked some locals for extras and happened to need a chubby girl for the dance scene. Poor thing was embarrassed at the high school reunion.
