Actor George Clooney has added his voice to the growing row about the all-white Oscar nominations, saying the Academy - and Hollywood in general - is "moving in the wrong direction" and is more racist than it was a decade ago. The announcement last week of the Oscar nominations has seen a wave of protest, with all 20 of the Best Actor and Best Supporting Actor nominees being white for the second year running.Clooney, 54, a six-time Oscar nominee who won as an actor for Syriana and as a producer for Argo, said African Americans, women and Hispanics were not being treated fairly by Hollywood."If you think back 10 years ago, the Academy was doing a better job," he told Variety magazine.Clooney's assertion that there were more African American nominations in previous decades is not supported by the records. At times seven or eight years would pass without a black actor being nominated in one of the categories, with black women particularly struggling for recognition.Halle Berry, in 2001, was the first black woman to win the Oscar for Best Actress, for Monster's Ball.Only four black men have won Best Actor awards: Sidney Poitier in 1963, Denzel Washington, Jamie Foxx and Forest Whitaker.Three black women have been nominated for Best Actress since 2005: Gabourey Sidibe for Precious, Viola Davis for The Help and Quvenzhané Wallis for Beasts of the Southern Wild - but none has won. ..
