The break even point is a lot more then $300 million dollars since they also spend $100 million in advertising the movie.

How do we know this exactly? Have they announced it or is it one of the many numbers flying around from "experts"?

That is a number flying around but movie companies usually never disclose the exact amount they spend in advertising for most movies the amount they spend on advertisng it is completely unknown.
