Errol Morris' latest Oscar-winning documentary is no Moore-style polemic but an artful interrogation of infamous US Defence Secretary Robert McNamara, who gave Morris 23 hours of filmed interviews in 2001, before 9/11 and the Iraq war, though unspoken parallels are hard to ignore. A formidable intellectual bruiser at 87, the old Cold Warrior seizes what may prove to be his last chance to make peace with history. Riveting.

Denys Arcand reunites the Quebecois characters who made '86's The Decline Of The American Empire so witty and engaging, and despite their age, disillusion and failing health, they're as intellectually provocative as before. Yes, it's talky, but as one lies dying, his friends reminisce about days of drugs and libido, and his son finds a backbone. A moving, note-perfect Oscar-winner.
