Spike Lee has criticised the lack of diversity in Hollywood, saying "it's 1950, it's Eisenhower".
The director attended the Sundance Film Festival for the premiere of Red Hook Summer, the fifth film in his "continuing chronicles of Brooklyn, N.Y".
He showed the film to a full house which included guests such as Chris Rock and Cuba Gooding Jnr, and announced that he was still frustrated at the lack of diversity in the entertainment industry.
He said that in the "upper echelons of television and studios, it's 1950. It's Eisenhower."
He thinks there is a lot of work to be done before the film industry reflects the diversity of the United States.
He noted that the US Census shows that "white Americans will be a minority by 2045, maybe sooner," and said it makes "good business sense" for companies, including entertainment companies, to diversify their workforce.
Red Hook Summer is a coming-of-age film about a teenager forced to swap his comfortable life for a summer spent with his Bible-bashing grandfather in a Brooklyn housing estate.
