Renée Zellweger worked long and hard to prepare for the role of Judy Garland for the biopic "Judy," out today. Zellweger credits her brief and fickle acting hiatus for her ability to appropriately prepare for the task of representing Garland as her big comeback: "I needed to not have something to do all the time, to not know what I’m going to be doing for the next two years in advance. I wanted to allow for some accidents. There had to be some quiet for the ideas to slip in," she told Vulture. "Judy," which follows Garland's life and career in the last year of her life, 1968, when she absconded to London to grab hold of some financial means. Will you need the film to understand Garland's life, or is she an icon you know all too well?
