“I ask Ehrenreich if it’s possible to go Day-Lewis deep on a character like this. “It’s easier than you’d think,” he says, “because there’s so much information on Star Wars. I did a movie about the Iraq War right before this, and there’s almost as much information about Star Wars.” He delved into Wookieepedia, a fan-curated online reference source that’s exactly what it sounds like. He likes the idea that everything the characters do in this film, every place they visit, will become part of the lexicon. They’re writing directly into the canon. “The wardrobe is a big part,” he says. “I remember doing my audition on the Falcon, putting on the jeans with the Corellian bloodstripe”—per Wookieepedia, “an award for conspicuous gallantry given by the Corellian military forces”—“and thinking, Oh, yeah. This is Star Wars. Like, this really is Star Wars now.”
