Oscar-Nominated Film Shows Nazi Rally at Madison Square Garden
It’s an unlikely Oscar contender. Marshall Curry‘s “A Night at the Garden” has been nominated for an Academy Award for Best Documentary Short. The film, entirely comprised of archival footage, shows a 1939 rally of American Nazis at New York City’s Madison Square Garden. The rally drew 20,000 people on the eve of World War II. “The lesson of the film,” Curry told InsideEdition.com, is that “we are vulnerable to leaders who will stir us up against each other.”
By Ari Feldman in Jewish daily Forward in the USA, 14 February 2019:
The 30-second ad, called “It Can Happen Here”, is for “A Night At The Garden”, a documentary short about a 1939 meeting of the German American Bund, a pro-Nazi organization. That infamous meeting, which gathered 20,000 people in New York’s Madison Square Garden, was a dramatic show of American support for Hitler — and of American anti-Semitism. Banners hung up in the Garden read “Stop Jewish Domination of Christian Americans”, and “Wake Up America. Smash Jewish Communism”. The crowd yelled “Seig Heil!”
But Fox News rejected the ad for the short, which is meant to warn that Nazism and fascism can happen in American. The ad, which Fox News’ leadership deemed “not appropriate,” was meant to be aired for [extreme right Murdoch-Fox employee] Sean Hannity’s show, historically the most-watched cable news broadcast.
“It’s amazing to me that the CEO of Fox News would personally inject herself into a small ad buy just to make sure that Hannity viewers weren’t exposed to this chapter of American history,” said Marshall Curry, the director of the short.
