George Lucas continued on the I-III part of the Star Wars franchise after The Phantom Menace (1999) with Attack of the Clones (2002).
It had been ten years since the failed invasion of Naboo and Anakin Skywalker became a Jedi student. However, Padme Amidala (Natalie Portman) was the victim of a failed assassination. Obi-Wan Kenobi (Ewan McGregor) and Anakin tracked down the killer and learned that she was hired by a bounty hunter known as Jango Fett (Temuera Morrison), whose DNA was used for a clone army for the Republic to stop the growing army of Separatists, led by Count Dooku (Christopher Lee) of the Sith.
Per fan’s requests, the Gungans and Jar Jar from The Phantom Menace had heavily reduced screen time.
Attack of the Clones is also quite political alongside Revenge of the Sith (2005) due to the ethical issues about cloning and going into war.
“Begun, the Clone War has.”
Attack of the Clones showed George Lucas in the prime of his time just before he completed Revenge of the Sith.
