‘Girl 27’ recalls how MGM called shots in 1937

Studios wield tremendous power today, but it’s nothing compared to how powerful they were 70 years ago.
In 1937, for example, MGM was the biggest employer in Los Angeles County and, according to filmmaker David Stenn’s powerful new documentary “Girl 27,” the studio was able to engineer the biggest cover-up in Hollywood history. It’s a fascinating story about the brutal rape of Patricia Douglas, an underage chorus girl who along with more than a hundred other young dancers was tricked by the studio into attending a stag party the studio held as part of a convention to reward hundreds of its salesmen from across the country for doing such a great job...
... In the footage of Louis B. Mayer greeting the sales people as they arrived there’s a man standing next to him in a police uniform. That’s L.A. police chief James Davis. So here you have Louis B. Mayer exhorting these guys to ‘have a good time, anything you want’ and he has the presence and, therefore, the endorsement of the Los Angeles Police Department’s chief right behind him.”...
... They protected the people within the studio and, in turn, the studio demanded and received complete loyalty. When I was doing the Jean Harlow book I was contacting a lot of people. I did several hundred interviews and occasionally you’d come across someone and you’d ask them a question and they would say, ‘Well, I would love to talk about that, but I don’t think Mr. Mayer would approve.’ And you would say to them, ‘Well, Mr. Mayer died in 1957 and that was (more than) 35 years ago.’ And they would say, ‘I’m sorry.’”
Girl 27 shows that many Hollywood powerbrokers were snakes-in-the grass just as Joseph P Kennedy was before, during, and after his Hollywood tenure. And his influence eventually led to his son gaining the White House.
