Pig Scrolls is based on a novel by Paul Shipton. It follows a talking pig and his attempts to save the world. Taking place in Ancient Greece, the book makes a lot of references to Greek mythology and it "includes all of the major Greek gods, as well as some minor deities."
In Dreamwork's version, the fate of the world, and of the Gods, will center on that talking pig.
Kirk De Micco (Space Chimps) did the most recent pass at adapting the script. Should Pig Scrolls be a box office hit Dreamworks owns the option on a sequel.
