Continuity: When men looking for radiation search the house, Karen and Dolly are questioned and Dolly is taken away. Soon afterward, in a close shot of Karen, Dolly is in the background.
Errors in geography: Kerr McGee's Cimmeron plant is on the east side of Hwy 74, between Crescent to the north and Oklahoma City to the south. Opening scenes show a mileage sign for Crescent, which is really the opposite direction. This also causes incorrect footage for placement and direction of travel in later scenes (ex. placement of car in accident, tow truck pulling wrecked car past Crescent Cafe, etc.)
