Well, it seems that they WOULD make more money off foreign and indie flicks simply because nearly all the proceeds from mainstream movies go to Hollywood. Cinemas pretty much only profit from the super-expensive popcorn and soda that they try to pawn off...

P.S. By squeezing movie theaters so hard, the movie industry is nearly killing them. But they don't care anymore because they know that people will buy the DVD to watch on their big-screen TV, even if there isn't a cinema around. (More people have been switching to home "theaters" anyway because of how expensive movie tickets have gotten-- and that price increase is mainly driven by Hollywood's demands for more money from the cinemas.)
