Rotten Tomatoes has a feature called "Average Tomatometer by Year," and the default screen for Renée Zellweger looks grim. From 2005 to 2009, her score drops for two years (from 80 to 52), recovers a little (to 64), and falls off a cliff (to 19).

This is completely meaningless, of course. If you expand the time frame, the line jumps up and down mercilessly. If you've ever heard of the trouble with a "small sample size," this is prime evidence, with most actors being in one or two movies a year. And Renée is but one person in movies containing (and made by) multitudes.

Still, there's the sneaking suspicion that Ms. Zellweger is on a downward trajectory. Her latest, the romantic comedy New in Town, finished in last place in our Box Office Power Rankings (won by Slumdog Millionaire), and new releases only landed in that spot eight other times over the past year. Entertainment Weekly's recent "Recall the Gold" survey wanted to steal her Oscar for 2003's Cold Mountain.

THE WRESTLER

Sure, lots of people love Mickey Rourke now. But if you're among those of us who were in thrall to the recent Oscar nominee's talent and charisma during the '80s glory days of Body Heat and Diner, and who followed him happily through the lurid thrills of Angel Heart and Barfly, and who despaired during his career debacles in the '90s, and who rejoiced whenever he managed to pop up again in the rare good movie, his greatness in director Darren Aronofsy's The Wrestler is likely to produce feelings of enormous gratitude - coupled, that is, with an almost inexpressible sadness, which comes from realizing what Rourke, and his fans, have lost over the past three decades.

FROST/NIXON

Ron Howard's adaptation of playwright Peter Morgan's Frost/Nixon has been nominated for five Academy Awards, and in Variety magazine, Morgan reacted to its success by saying, "The film is political but entertaining, and the credit goes to Ron. He takes the experience the audience has at the cinema very seriously." That's why I love Howard, and also why, as a director, he drives me absolutely crazy.

NOTORIOUS

Every musician's life is different, of course, but every musical bio-pic seems fundamentally the same: The humble beginnings, followed by the first hints of greatness, followed by the early romantic interests, followed by the steady rise to fame, followed by the new romantic interests, followed by the explosive success, followed by the personal setbacks, followed by the professional setbacks, followed by the cementing of the legend ... and if the movie can find room for a title card reading "With his life he proved that no dream is too big," so much the better.
