Question: how many calories in a large popcorn at the movie theatre?
Answer: A large AMC popcorn, without butter, contains 1,030 calories and 41 grams of fat. Moving along to Regal Cinemas, things get even heavier. There are a couple of differing calorie counts for a small, unbuttered popcorn, but they range from 325 calories and 27 grams of fat to 670 calories and 34 grams of fat.
