Jared Leto has won the 2014 Oscar for Best Actor in a Supporting Role for his performance in Jean-Marc Vallee's drama film "Dallas Buyers Club," marking the 42-year-old star's first win and nomination.
The winners were announced at a live ceremony that took place at the Dolby Theatre in Los Angeles and aired live on ABC on Sunday, March 2. Leto beat Barkhad Abdi of "Captain Phillips," Michael Fassbender of "12 Years A Slave," Bradley Cooper of "American Hustle" and Jonah Hill of "The Wolf of Wall Street."
Leto thanked his mother, Constance, who had accompanied him to the Oscars, along with his brother, Shannon (watch a video of them walking the red carpet, below).
"In 1971, Bossier City, Louisiana, there was a teenage girl who was pregnant with her second child," he said. "She was a high school dropout and a single mom, but somehow she managed to make a better life for herself and her children. She encouraged her kids to be creative, to work hard and to do something special. That girl is my mother and she's here tonight. And I just want to say, I love you, Mom. Thank you for teaching me to dream."
"To my brother, Shannon, the best big brother in the world, you're a true artist," he said. "Thank you so much for sharing this insane and amazing adventure that is 30 Seconds to Mars, and for being my best friend. I love you. Thank you."
"To all the dreamers out there around the world watching this tonight in places like the Ukraine and Venezuela, I want to say we are here and as you struggle to ... to make your dreams happen, to live the impossible ... We're thinking of you tonight. And this is incredibly special as well because there's so many people that helped me get here."
In "Dallas Buyers Club," Matthew McConaughey plays an HIV-positive patient named Ron Woodroof who smuggles from other countries anti-viral medications that are not approved in the U.S. Leto plays Rayon, a transgender AIDS patient with a heart of gold. The two secretly sell the drugs to fellow patients. Both actors lost a significant amount of weight for their roles.
"This for the 36 million people who have lost the battle to AIDS and to those of you out there who have ever felt injustice because of who you are or who you love, tonight I stand here in front of the world with you and for you," Leto said. "Thank you so much and goodnight."
Leto later joked backstage with reporters, offering to allow them to "fondle" his Oscar statuette and thanked his fans, The Echelon, during an interview with OTRC.com. (Watch videos, above).
Leto, who is the frontman of the rock group Thirty Seconds To Mars, had in 2009 taken several years off from his acting career to concentrate on his music before returning to acting last year. He is previously known for playing Jordan Catalano in the short-lived 1990s series "My So-Called Life" and for his roles in movies such as "Requiem For A Dream" and "Girl, Interrupted."

Before the Oscars, Leto talked to OTRC.com on the red carpet about talking to U2 frontman Bono at a luncheon for the Oscar nominees in February.
"The secrets that he told me .. he swore me to secrecy," Leto said. "It's great to talk to some of your heroes like that."
