Percy Jackson & the Olympians: The Lightning Thief (2010)

Percy Jackson is an average teenager who suffers from dyslexia and ADHD. On a trip to the museum, his teacher Mrs Dodds takes Percy aside but then transforms him into fearsome winged creature and attacks him. Percy is saved as his best friend Grover and the teacher Mr Brunner drive away the creature, which they call a Fury. They take Percy to the remote Camp Half Blood for his own protection. There Grover reveals that he is a satyr, a mythical creature with the legs of a goat who has been appointed as Percy’s protector, while Mr Brunner is revealed to be the centaur Chiron. Mr Brunner tells Percy that he is a demi-god, the son of the Greek god Poseidon and a mortal woman. Someone has stolen Zeus’s lightning bolt – with some of the gods believing that Percy is the thief – and the world will be plunged into chaos unless it is found within fourteen days. Percy begins training, discovering his abilities, including how to gain great power from water. But then Hades appears, demanding the lightning bolt and revealing that he has Percy’s mother in the underworld. And so Percy sets out to rescue her, joined by Grover and Athena’s daughter Annabeth, a fierce warrior. To enter Hades they need to go on a quest to obtain the three pearls that will allow them to escape once there. Their quest requires entering the garden centre run by the Medusa, stealing a pearl from where it is guarded by the Hydra at The Parthenon in Nashville, and travelling to a Las Vegas casino where after eating lotus cakes people are lulled into a blissful dream and never leave... Based on the book by Rick Riordan.
