                                A small buttered theater popcorn can contain anywhere from 315 to well over 500 calories, depending heavily on the theater chain and the amount of butter-flavored topping applied. This wide range is a result of variations in popping oil, portion sizes, and the surprisingly high-calorie faux butter used at concessions.
