Oscar Isaac stopped by Late Night With Jimmy Fallon last night on December 9th to promote his new film Inside Llewyn Davis. I’ve added a few stills and screen captures of his interview, massive thanks to my friend Luciana at Jessica-Chastain.com! If you happened to missed it, you can catch the last few minutes of his interview below where Oscar performs “Roar” by Katy Perry! Inside Llewyn Davis is now playing in selected theaters in LA and New York, and additional cities on December 20! For tickets, click here!
