Lindsay Anderson was first a film critic and always a film critic. Even when he directed the fiction films This Sporting Life, If, O Lucky Man and The Whales of August, he displayed an awareness of film as both art and social statement. That’s the significance of the Film Society of Lincoln Center’s current Anderson retrospective through Aug. 21. It features the theatrical premiere of Never Apologize, a bio-doc in which actor Malcolm McDowell reads the British director’s journals and reminiscences.
