Performance artist Marina Abramovic speaks during an interview at the Rio Film Festival in Rio de Janeiro, Brazil, Thursday, Oct. 4, 2012. The Belgrade-born artist is best known for her piece "The Artist Is Present," which in 2010 saw her sit silent and motionless for 736.5 hours opposite a parade of strangers at New York's Museum of Modern Art. The film is playing at the 2012 Rio de Janeiro International Film Festival. (AP Photo/Silvia Izquierdo) less
