Speaking of the awards season... Clint Eastwood's Letters from Iwo Jima, the companion film to this fall's earlier-released Flags of our Fathers, has been named best picture by the National Board of Review. Martin Scorsese was named best director for The Departed, while Forest Whitaker ( Last King of Scotland) and Helen Mirren ( The Queen) nabbed the top acting prizes. Volver won best foreign film, Al Gore's An Inconvenient Truth was declared top documentary, and Cars led the animated-entries pack.
