Ewan McGregor watched the entire Skywalker saga to get ready for the show, but Christensen went even deeper.

It could be familiarizing oneself with the original source material.

It could be researching the character.

It could be long conversations with a director about backstory and motivation.

But what about when you are returning to a character you already played, albeit 17 years ago?

Any of the old films?

Tryallof them, even the ones his character wasn’t in.

“I watched them from start to finish,” McGregor says.

“All nine movies.

Just to get back in that world.”

(Sorry,Rogue OneandSolo, looks like you didn’t make the cut.)

It turns out this was the first time McGregor watched the prequels since they were originally released.

That’s not the only prep McGregor did; he also delved more into the entire genre.

“I started reading science fiction,” he reveals.

“Iain M. Banks is a Scottish writer, and I started reading his science-fiction novels.

I kind of didn’t do it the first [time].

And it’s not something I would normally do, but this time I did.

I got jazzed about being back in space because I really love it as a movie watcher.”

While McGregor went back and watched the entire Skywalker saga, Christensen went even deeper into theStar Warscanon.

“And I also got into the animated shows,The Clone WarsandRebels.”

“It was interesting,” Christensen says of bingingThe Clone WarsandRebels.

“They did a lot with these characters in those shows.

And they did further explore the relationship.

There was interesting stuff there to learn about.

Some might even call his research impressive… most impressive.
