Percy Jackson & the Olympians: The Lightning Thief, where dyslexia means you can read Ancient Greek and ADHD just means you need to cool your jets underwater. Based on the children's novel of the same name, Percy Jackson & the Olympians: The Lightning Thief follows the titular hero as he first discovers that he's the son of Poseidon and then sets out to recover Zeus' lightning bolt with the help of his demigod girlfriend and satyr best friend. Percy Jackson boasts a star-studded cast -- including Uma Thurman, Pierce Brosnan, and Rosario Dawson -- that pops up in surprising places.
