Over four days - 25 to 28 April - the second Sundance London presents four exciting days of live music, the UK premieres of American independent films fresh from the 2013 Sundance Film Festival, plus panel discussions, filmmaker Q&As and special events.
One of the strongest strands is the section dedicated to documentaries, including one charting the personal journey of actress Mariel Hemingway.
'Running From Crazy' chronicles the life of Hemingway, the granddaughter of the novelist Ernest Hemingway. The film focuses on Mariel's family history of mental illness, drug addiction, and the suicides of seven relatives, including her grandfather and her sister, Margaux. The stakes are high, as Mariel attempts to ensure the fate of herself and her children is a very different one.
