Groucho engaged in long cons, often involving wooing wealthy dowager Margaret Dumont.
Harpo played his mute, addled sidekick, who liked to chase women while honking a horn. He also handed random people his leg.
Wait -- Zeppo falling in love with a woman, Groucho wooing a woman, Harpo chasing women. Granted, the wordplay came fast and furious, pretensions were deflated, social institutions were mocked -- but wasn't it still heterosexist?
Not at all. You can queer a Marx Brothers movie as easily as Making Love.
1. You don't expect a lot of beefcake in movies from the 1930s, but there was some. Mostly from incidental players.
2. In the heart of the Pansy Craze, there are no pansy jokes No screaming queens, no effeminate waiters, none of the overt homophobia evident in other movie comedies of the era.
3. Zeppo's hetero-romance is ludicrously over-the-top; it is one of the social institutions that the Marx Brothers are mocking.
Groucho woos Margaret Dumont for her money; elsewhere, his jabs and hints hit men and women both. "Tell me, what do you think of the traffic problem? What do you think of the marriage problem? What do you think of at night when you go to bed, you beast!"
Harpo hands his leg to women and men both.
Chico doesn't seem particularly interested in women.
All of the Marx Brothers demonstrate an easygoing nonchalance about same-sex desire that is remarkable for the period.
My friend Randall claimed to have been with him at a party in Hollywood in 1958.
Near the end of his life, the 80-year old Groucho fell in love with 30-year old Bud Cort -- who starred in Harold and Maude (1971), about a romance between a teenage boy and an elderly woman. Bud moved into Groucho's mansion, where the question of whether they became physically intimate is nobody else's business. "I loved him, and he loved me. He was my fairy godfather."
