Because of Disney's actions, you're in a no-win scenario with Dinosaur. If you consider it a success, it just makes the decision to stop doing "CGI" all the more boneheaded. (A decision that has since been reversed)
#42 all-time isn't bad, but you also have to factor in the budget (including marketing), which I'm quite sure would be higher than #42 all-time.
On LOTR and Jackson, I've read in several places that they had an agreement with Miramax to do 2 movies, but Miramax needed
Disney's approval. Disney said nope, only one movie.
Jackson was given a deadline and was told if he could get somebody else to make the deal he wanted, he could go with them. 1 or 2 days before the deadline, New Line came on board and asked why they were only doing 2 movies when there are three books. So Jackson got his deal before the deadline, with the Weinsteins retaining executive producer credits, and getting a nice check...in effect, a buyout.
Not that I believe everything I read of course, but I haven't read anything that says Jackson was demanding a 3 pic deal. I think he WANTED a 3 pic deal, but had essentially agreed with Miramax on the 2 pic deal.
