Last month, the venerable Sun-Times film critic Roger Ebert was too ill to make it to his annual Ebertfest. The festival must've felt a bit like his cherished Up documentaries: full of enjoyable new developments, but somewhat incomplete due to events beyond one's control. Ebert still contributes thoughtful analysis twice a month for his Great Movies column, but it's hard not to miss those compulsively readable regulars — which were often more memorable than the films themselves (North, anyone?). He's up and about again, so wish him a speedy recovery at tonight's signing of his latest book, Four-Star Reviews (1967-2007).
