It’s the Oscars tonight, which is good news for insomniacs because it’s likely to run through to breakfast. The film tipped to take the top honours – it has 10 nominations – is Mank. If it wins Louis B Mayer, who originally set up the Academy Awards, will be be turning in his grave. Mayer created and ran MGM, the biggest Hollywood studio ,which led in the blacklisting of the Hollywood 10 in 1947, accused of being communists. And in the 1930s, amazingly as he was a Jew, he collaborated with the Nazis to censor anything critical. He and other studio heads met with the German counsel in Los Angeles who sent reports to officials in Berlin about the cuts the studios had agreed to make.
