Was Hitler gay? In The Hidden Fuhrer: Debating the Enigma of Hitler’s Sexuality, based on German historian Lothar Machtan’s book, The Hidden Hitler, the evidence would seem to say ja. PlanetOut.com says the WOW documentary, which includes numerous interviews, recently discovered archival documents, and rare footage and photos of Hitler, including his artwork, is perhaps WOW’s most academic work to date. Heil drink to that. The doc airs on Cinemax April 20, Hitler’s birthday.

[The film digs] up an extensive amount of evidence, including a report from an eyewitness from the trenches of World War I who said he caught Hitler having sex with a fellow soldier, a top secret file from Munich’s vice squad that alleges Hitler paid young men for sex and accounts from several of Hitler’s closest friends — some of whom were gay — insisting that he was a homosexual.
