I was wrong on the projected marketing budget. See the link below for the costs involved in making The Dark Knight Rises. It states the marketing costs were $175 million. Marketing for The Odyssey is going to be higher.

Studios keep about 60% of the domestic box office and 20% to 50% of the overseas box office, depending on the country (you are lucky to get 20% of the Chinese box office). It balances out to about 50% of the box office goes back to the studio.

My low end estimate of $400 million for production and marketing means they will have to make around $800 million to break even.
