Alfonso Cuaron and Gravity added top film honors to their collection at last night's Directors Guild of America Awards, building momentum in what's seen as a tight three-way race to the Oscars. The award all but guarantees Cuaron the Best Director Oscar (though don't ask Ben Affleck about that particular almost-guarantee), and gives Gravity another boost over American Hustle and the faltering 12 Years a Slave, notes the AP. The latter two films had been seen as the strongest contenders in a flip-a-coin contest at the March 2 Academy Awards, but as Scott Bowles at USA Today notes, "Now the coin has three sides."
