Legion357 is right, he knows why the concession is so expensive.
Most of the money that a theatre takes in from ticket sales goes back to the movie studio. The studio leases a movie to your local theater for a set period of time. In the first couple of weeks the film shows in the theatre, the theatre itself only gets to keep about 20% – 25% of the green.
Star Wars Episode II: Attack of the Clones, the studio took 100% of the box office take for the first week of release.
Into the second and third weeks of release, the percentage starts to swing to anywhere from 45% – 55% that the theatre gets to keep. It gets better after the fourth week when theatres generally can keep up to 80% or better of the ticket sales. I don’t know about you, but when I finally get around to seeing a film that’s already been in the theatres for 4 or 5 weeks, I’m usually one of the only people in the place. It doesn’t do the establishment a lot of good to keep 80% of the ticket sales when only 14 tickets are sold per show. And with more and more and more movies getting released every week, the length of time that a movie stays in theaters is shrinking. Bad news for the movie theaters.
Movie theaters are then forced to really make their money off concessions. One theater manager said “We’re not in the movie business… we’re in the candy business”.
don't mind paying for the movie tickets, it's the concessions that kill my pocket book.
