Jake Gyllenhaal is on a crusade to become the most complete performer in the world, or at least that’s how it’s starting to seem. The Oscar-nominated actor has an unusually impressive resume, littered with filmmaker-driven and script-driven choices among the occasional misguided blockbuster. He’s undergone tremendous physical changes for films like Nightcrawler and Southpaw. He served double duty in dual roles for Denis Villeneuve’s Enemy. And now, he’s apparently fantastic at musical theater, too.
