n">British actor Joseph Fiennes has been cast as iconic African-American pop star Michael Jackson in an upcoming TV comedy, provoking scorn on social media on Wednesday and fueling a controversy in the entertainment industry over opportunities for black artists. Fiennes, who is white, will play the late "King of Pop" in an apparently real-life story for Britain's satellite TV channel Sky Arts about a road trip across the United States the singer is said to have taken in 2001 with movie stars Elizabeth Taylor and Marlon Brando.
