Jared Leto has won the Academy Award for Best Supporting Actor Sunday for his portrayal of Rayon, a transsexual prostitute with AIDS, in Dallas Buyers Club.

It's Leto's first Oscar, but he made a clean sweep of the Golden Globes, the SAG Awards, the L.A. Film Critics' Association Awards and New York Film Critics Circle Awards. His fellow Supporting Actor nominees were Michael Fassbender in 12 Years a Slave, Barkhad Abdi in Captain Phillips, Jonah Hill  in The Wolf of Wall Street and Bradley Cooper in American Hustle.

“To all the dreamers out there watching this tonight in places like the Ukraine and Venezuela, as you struggle to make your dreams happen, and live the impossible, we’re thinking of you tonight,” said Leto in his speech.

He recalled his mother's sacrifice as a single mom in the early 1970s, and dedicated his award to “the 36 million people who have lost the battle to AIDS, and to all people who have lost a battle due to injustice, due to who they are or who they love.”
