Quick, what’s the most important element to the enduring success of the Star Wars universe? Jedi? Good guess, but nope. Stormtroopers? Close, but still no. Give up? For my money, the success of the Star Wars universe is owed to the endless supply of talented and high-profile European actors who are willing to add gravitas to the cartoonish aims of the Empire and the First Order. To quote comedian Eddie Izzard, the Death Star is teeming with ‘British actors opening doors,’ and that’s part of what makes the entire thing seem way more substantial and lived-in than it really is.
