The first trailer has arrived for "Judy" starring "Bridget Jones" star Renee Zellweger as "The Wizard of Oz's" Judy Garland. The biopic tells the story of her final concerts in London.There's no dialogue in the trailer, but we do hear Zellweger's take on the classic song, "Over the Rainbow." Set in 1968, the icon arrives in London for her sell-out run show, "The Talk of the Town," 30 years after "The Wizard of Oz."During the preparation for her shows, viewers see her battle with management, reminiscing with fans and starting a romance with Mickey Deans, her soon-to-be her fifth husband. But Garland is exhausted and haunted by memories of a childhood lost to Hollywood."Judy" also features rising star Jessie Buckley, Rufus Sewell, Finn Wittrock ("American Horror Story"), Michael Gambon and Bella Ramsey (Lyanna Mormont from "Game of Thrones") as Garland's daughter, Lorna Luft.Based on a script by "The Crown's" Tom Edge, the biopic will feature some of Garland's best-known songs and is directed by Rupert Goold.Before the release of "Judy," Zellweger will be seen in Netflix's "What/If" where she plays the leader of a "dangerous game," offering the players the chance to live their wildest dreams, but only if they are willing to risk it all."Judy" will be released September 27.
