The megastar was the surprise guest at the film's premiere last night during the New York Film Festival.
'She was wiping away tears after the movie,' a fellow festivalgoer says. 'She said she loved the movie.'
Madge didn't hit the red carpet during the evening's celebrity arrivals. Instead, she took photos with 12 Years director Steve McQueen backstage before slipping into the theater right as the movie began.
The movie tells the true story of Solomon Northup, a free man from New York who was abducted and sold into slavery in 1841. He survived working on plantations in Louisiana for 12 years before he was released. Chitwetel Eliofor stars as Solomon with Michael Fassbender as his brutal slave owner. Both are already big Oscar contenders, as is Lupita Nyong'o, the film's breakout star who plays a slave named Patsey. Brad Pitt, who has a small role in 12 Years, is one of the movie's producers.
