I also think the 300 million figure sounds right. Which is almost unbelievable for a religious film that is spoken in foreign languages with subtitles that is also r-rated.
As for Mel, its great to see someone willing to put his money where his beliefs are and bankroll a movie hollywood wanted nothing to do with and the hollywood power structure(including disney)did everything they could do to scuttle the movie. Its easy for hollywood stars to get a big paycheck and then preach, but its a big difference when ones uses his OWN money to bankroll a project they believe in.
As an aside, its a excellant movie and well worth seeing more than once!!! A very moving movie!!
