Back in 1984, Terry Gilliam’s sci-fi masterpiece ‘Brazil’ was the focus of a furious campaign by US critics when its producers refused to allow the film to screen to US audiences. This week, a similar groundswell is building around the ‘new’ film from ‘You Can Count on Me’ director Kenneth Lonergan. On extremely limited UK release this week, ‘Margaret’ stars Anna Paquin, Matt Damon, Matthew Broderick and Mark Ruffalo in the tale of a young, privileged New York teenager whose life becomes wildly unpredictable when she witnesses an horrific bus crash. The film was shot in 2005, has been caught in legal limbo ever since, and has allegedly been recut against Lonergan’s wishes, but what remains is still an extraordinary achievement: an ambitious, insightful, scattershot but deeply affecting drama of real lives in transition. Read the 5-star review by Time Out New York’s Keith Uhlich and, if you feel strongly enough, campaign to give the film a wider release and awards consideration by signing the petition. Tom Huddleston
