Hollywood’s a shady place sometimes. Artists, craftsman, politicians, and businessmen from all over the world converge on Los Angeles, California, ready to do battle over the almighty dollar.

Hollywood’s history is a story of backroom deals and secret affairs as tantalizing as anything the studios have churned out on film. Here are the ten best secrets Hollywood ever kept.

1. A Lot of Silver Screen Movie Stars Were Gay

Today we cheer when a rising star like Ellen Page declares to the world that she’s out and proud, but there was a time when even a suggestion of homosexuality was a death sentence for anyone’s career.

For whatever reason, theatrical communities have always had a thriving gay populace, and many of these talents found they had to keep their private lives private if they wanted to make the leap to the big screen.

For instance, actor Rock Hudson was a well known homosexual behind the scenes of Hollywood, and had to keep careful watch of what the media said about him.

Hudson never officially came out, but he became one of the first celebrities to die of AIDS-related illnesses in 1985.

Randolph Scott and Cary Grant famously lived together off and on for over ten years, leading to rumors of homosexuality that persist to this day. There are even accounts that acting gods Marlon Brando, Alec Guinness and Lawrence Olivier were bisexual at the very least.

Brando admitted to having homosexual encounters during his life, though he never said who, but on the whole we’re left only with hearsay and secondhand accounts of who was gay and who was straight.
