Do you need to eat anything at a movie theatre? I know, I didn't grow up in North America so the popcorn and soda combo while watching a movie is not engrained in me so deeply as in others. But I make a habit of go to the movies after I had dinner (or another meal) and I don't feel the need to snack.
At Christmas, when I was in the US, we went to see a movie after picking up a few things at Walmart and I was mentally smacking myself senseless for having not purchased some bottled water at Walmart. When we got to the movie theatre I was suddenly thirsty and I got extremely annoyed when they charged me $4.50 for a bottle of plain Asani water (x2, a bottle for each of us). Bloody murder! As a rule, I don't buy anything at a movie theatre so I didn't even know how expensive things got there.
If you MUST snack, why don't you make some trail mix at home (better home-made than the pre-fab purchased one) or bring some almonds or other nuts.
