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

Teenager Percy Jackson discovers he’s not just an ordinary kid — he’s a demigod, the son of Poseidon, god of the sea. When Zeus’s lightning bolt, the most powerful weapon in the universe, is stolen, Percy becomes the prime suspect.
To clear his name and prevent a war among the gods, Percy embarks on a cross-country quest with his friends Annabeth, daughter of Athena, and Grover, a satyr protector. Together, they face monsters from Greek mythology, uncover hidden truths, and confront powerful enemies.
A modern-day adventure where myth meets reality — and a hero is born.
