Oscars host Chris Rock faces tricky balancing act of humor and diversity

By Jill Serjeant NEW YORK (Reuters) - Hosting the Oscars is seen as the ultimate honor in show business but no one has a trickier task of balancing humor, diversity politics and celebrating movies on Sunday than Chris Rock. Rock, a black stand-up comedian and former "Saturday Night Live" cast member, was chosen to host Sunday's Academy Awards for a second time last October - long before the #OscarsSoWhite furor that has overshadowed the biggest annual celebration of the movie industry. "I think Chris Rock will address the diversity issue head on, which is exactly what the show and the Academy need." Rock, 51, has kept silent during the uproar over the 20 all-white actors nominated this year.
