Question: how many calories in a large popcorn at cineplex?
Answer: AMC, a U.S. based company, did not return my calls. Cineplex Odeon says its large popcorn, no topping, has 850 calories, 40 grams of fat and 399 milligrams of sodium -- a difference of 291 calories, 27 grams of fat and 729 milligrams of sodium (half a day's worth).
