Best actor and best actress nominees Brangelina are among the arrivals at the British Academy Awards in London, which get under way in less than an hour. “Slumdog Millionaire,” natch is the heavy favorite to win best picture. Last night, the little movie that could added the Writers Guild of America award to prizes from the Producers Guild of America, the Screen Actors Guild and the Golden Globes. In case you were thinking of watching the BBC American broadcast tonight, a five-hour tape delay at 8 p.m. Eastern, I will be noting the big winners as soon as they move on the Beeb’s website.
