Ewan McGregor sat in George Lucas’s office in 1999 staring at a script filled with political dialogue about trade disputes and Senate procedures. “The lightsaber fights were easy,” he told me recently. “Memorizing 12-minute exposition scenes about galactic taxation? That nearly broke me.”

Dialogue
Star Wars prequels difficult scenes weren’t the elaborate action sequences fans might expect. McGregor reveals that Lucas’s dense political storytelling created the biggest acting challenges across all three films.
“George would write these massive monologues about the Republic’s governmental structure,” McGregor explained. “I’d spend weeks memorizing speeches about trade federations and emergency powers. The Jedi stuff was fun – the politics were torture.”
Attack of the Clones featured a 7-minute scene where McGregor’s Obi-Wan explains the clone army’s origins to the Jedi Council. The sequence required 23 takes because McGregor kept stumbling over Lucas’s complex terminology and made-up governmental systems.
The Star Wars prequels difficult scenes data shows McGregor had 347 lines of pure exposition across the trilogy – more dialogue than most actors deliver in entire films. His character served as Lucas’s primary vehicle for explaining the galaxy’s political transformation.
Technical Challenges
Beyond dialogue, the Star Wars prequels difficult scenes involved extensive blue screen work that McGregor found psychologically exhausting. “I’d be talking to tennis balls on sticks, pretending they were other Jedi or alien creatures,” he recalled.
The Kamino sequences in Attack of the Clones required McGregor to interact with entirely digital environments and characters. He spent 6 weeks filming against blue screens, never seeing the finished planet until the film’s premiere.

Lucas’s directing style compounded these challenges. The filmmaker rarely provided emotional context for scenes, expecting actors to find motivation through technical dialogue about hyperdrive mechanics and Sith history.
Character Evolution
McGregor’s biggest struggle involved bridging the gap between his younger Obi-Wan and Alec Guinness’s original performance. The Star Wars prequels difficult scenes required showing how a passionate young Jedi becomes the wise hermit of A New Hope.
“George wanted Obi-Wan to mature visibly across three films,” McGregor noted. “But the scripts focused more on plot mechanics than character development. I had to find the emotional journey between the lines.”
The Mustafar lightsaber duel with Hayden Christensen in Revenge of the Sith took 3 months to choreograph and film. But McGregor considers his final scene with baby Luke more challenging – conveying 20 years of upcoming isolation and regret through facial expression alone.
McGregor’s reunion with Lucas for the Obi-Wan Kenobi Disney+ series allowed him to explore the character’s emotional trauma between the trilogies. “Finally, I got to show Obi-Wan’s pain rather than just explain galactic politics,” he said.
Legacy Perspective
Twenty-five years later, McGregor appreciates how the Star Wars prequels difficult scenes served the larger saga’s themes about democracy’s fragility and power’s corruption. “George was telling a complex political story through space opera,” he acknowledged.
The prequel trilogy’s reputation has improved significantly, with younger fans appreciating Lucas’s ambitious world-building and political commentary. McGregor’s performance anchors much of that reevaluation.
“Those exposition scenes that nearly killed me to memorize turned out to be some of fans’ favorite moments,” McGregor laughed. “Kids quote Obi-Wan’s political speeches at conventions. George knew what he was doing.”
