An awarding scene on 42nd National Board of Review, first of the big annual awards, names its winners in December, but gala came Tuesday. Last arrival,  DiCaprio . I didn’t recognize him. He sped in. No model around him or attached to his various parts. Maybe she was at the table. Maybe elsewhere. Maybe actors even sometimes have an off day. Or night. Or weekend. Or crappy audition. Leo nabbed best actor for his thriller “One Battle After Another,” where he’s playing a counter culture activist.
