The movie takes place in Colorado just before Christmas, and yet, the only time you see real winter (bare deciduous trees and snow) is on the stock footage which production overused to mask that movie was shot in autumn. In the downtown, park, and around Gage's house, you can see a lot of greenish and yellowish deciduous trees. Used snow is clearly artificial as is different from the real one. The most revealing scene that it was shot in autumn is when Madison visited car service, and on the wide shot you can see mountain full of mostly yellowish deciduous trees. Also cast and extras didn't even have the proper winter cloths, and it can be very cold in the mid of December in Colorado - most of the time cast even had opened jackets, and barely anybody had hat in the outdoor scenes as it was obviously warm.
