Benjamin Button does look good - most of Fincher's movies are good ones.
I cannot understand Valkyrie opening on Christmas Day. Looks like a good movie and may improve Tom Cruise's public image, but a movie about Nazis on Christmas seems a bit risky. Interestingly, the German film community were initially opposed to allow filming at historic locations, possibly due to Cruise and his religious views. But they eventually were permitted, and in fact had to re-shoot the execution scene due to a film lab error. They should have shot digital!
