The Tale of Peter Rabbit was first published in 1902, which means almost every person with access to books has read it ot had it read to them. Seems like a solid audience to aim at for a big, Hollywood family movie, which may have something to do with the reason why Sony Pictures has announced it’s making a live-action and animated hybrid film based the Beatrix Potter novels.
