There seems little doubt that 2011 belongs to Ryan Gosling and Jessica Chastain. The previously unassuming-looking actor is in no fewer than three movies playing in theaters now. He surprised as the smooth ladies’ man in “Crazy, Stupid, Love,” he held us rapt with few words in “Drive,” and he held his own against George Clooney in “The Ides of March.” The red-headed actress has had a similarly spectacular year. She was one of the only authentic things about “The Help,” she got tough and vulnerable, channeling Helen Mirren, in “The Debt,” and she held her own against Brad Pitt in “The Tree of Life.”
