Percy Jackson grows up fast

“Percy Jackson & the Olympians: The Lightning Thief” will bring the bookshelf bestseller to the screen, but he’s not quite the magical child familiar to the millions of young readers of author Rick Riordan. In the books, the hero is 12, but in this new Hollywood adventure, the actor is 18-year-old Logan Lerman. On the Hero Complex blog, director Chris Columbus talks to Rachel Abramowitz about the age issue and says that, in a way, Lerman takes Percy to an even older sensibility. “He’s like this 45-year-old guy trapped in a teenager’s body. He’s wise beyond his years.” www.latimes.com/herocomplex.
