Did George Lucas directed all six Star Wars movies?

No, George Lucas did not direct all six Star Wars movies. He directed the original trilogy (Episodes IV-VI) but not the prequel trilogy (Episodes I-III).

Here's a breakdown:

* George Lucas:

* Directed: Episode IV - A New Hope (1977), Episode V - The Empire Strikes Back (1980), Episode VI - Return of the Jedi (1983)

* Other directors:

* Episode I - The Phantom Menace (1999): Directed by George Lucas

* Episode II - Attack of the Clones (2002): Directed by George Lucas

* Episode III - Revenge of the Sith (2005): Directed by George Lucas

While George Lucas was involved in the development and production of the prequels, he chose to hand over the directing reins to other filmmakers for those episodes.
