The film is set ten years after the Battle of Naboo, when the galaxy is on the brink of civil war. Under the leadership of renegade Jedi Master Count Dooku, thousands of systems threaten to secede from the Republic. When an assassination attempt is made on Senator Padmé Amidala, the former Queen of Naboo, Jedi apprentice Anakin Skywalker is assigned to protect her, while his mentor Obi-Wan Kenobi is assigned to investigate the assassination attempt. Soon the Jedi are drawn into the heart of the Separatist movement, and the beginning of a new threat to the galaxy: the Clone Wars.
Attack of the Clones was the first Star Wars film to use a high-definition digital 24-frame system for most of the its live-action scenes. The film was a financial success, grossing over $600 million at the worldwide box office. However, for the first time, a Star Wars film did not earn the highest box-office sales for the year; Attack of the Clones ended up fourth behind The Lord of the Rings: The Two Towers, Harry Potter and the Chamber of Secrets, and Spider-Man.
