I was going to ask you if they tracked DVD rentals! Or rather, if there was a way to see what something grossed. EII doesn't sound too bad, and I know people are still renting it, because I keep finding blogs written by people who just saw it. Same thing for GSH (and a good number of them are positive reviews, too). A pity there is no information for GSH rentals; I'd be interested to know what they were/are like.

What about DVD sales? Is there anywhere that tracks that?

I think it's pretty cool that Happy Feet can still be found in the theatre, especially since they've already released the DVD.
