PERCY JACKSON & THE OLYMPIANS: THE LIGHTNING THIEF
Just because the title is rather unwieldy, and the film is about an adolescent with otherworldly abilities, and this kid has male and female tag-along pals with powers of their own, and there are a lot of CGI effects on display, and the director is Harry Potter & the Sorcerer's Stone and Harry Potter & the Chamber of Secrets helmer Chris Columbus, don't think that Percy Jackson & the Olympians: The Lightning Thief is necessarily indebted to J.K. Rowling. The latest Harry Potter movie, after all, found its hero contending with a Half-Blood Prince. This adventure, on the other hand, finds its son-of-Poseidon protagonist attending Camp Half-Blood. See? They're not even remotely similar.
