The last 24 hours have been rather hectic for Mahershala Ali. Not only did he win the Best Supporting Actor Academy Award for his performance as Juan in Moonlight, but he was right in the thick of the action when Warren Beatty and Faye Dunaway accidentally announced that La La Land had won Best Picture. But that's now firmly in the past, because Mahershala Ali's future looks remarkably bright, too. That starts with his role in Alita: Battle Angel, which it turns out is much bigger than we originally thought because he will actually be playing two parts in the film.
