Ten years ago, who would have predicted that Mary Kate and Ashley Olsen would be relegated to irrelevance, while their younger sister Elizabeth would be the one with the promising acting career? Over the past few years, she has caught the attention of Hollywood with a string of powerful performances in independent films, before being cast as the Scarlet Witch in the second Avengers movie. But that's not the only thing she's got on her plate for 2015. She's also set to appear in I Saw the Light, a biopic about Hank Williams, where she will act alongside her Age of Ultron co-star Tom Hiddleston (who will be playing Hank Williams himself).
