But the biggest news may be the cost structure behind the fourth and fifth installments of Summit’s blockbuster Twilight franchise. “Breaking Dawn 1” will cost $127.5 million, but according to the documents Summit only has $38.4 million at risk. The film will be released in November 2011. The second film, “Breaking Dawn 2,” cost $136.2 million, with Summit’s exposure limited to $51.2 million, according to the documents. The studio anticipates revenues of $1.2 billion related to just those two pictures, the documents say. They are projecting a profit of $228 million for the first film and $219 million for the second for a total of nearly $450 million.
