Joaquin Phoenix wins Oscar for Best Actor in 'Joker' Read his Speech here

Hollywood star Joaquin Phoenix finally ended his dry run at the Oscars as he picked up the best actor trophy for his performance in and as "Joker" at the 92nd Academy Awards.

The 45-year-old actor had earlier bagged a BAFTA, a Golden Globe and a Screen Actors Guild Award for his turn as a failed, unhinged stand-up comedian who descends into chaos.

In a lengthy and rambling speech, Phoenix touched upon racism, climate change and gender inequality. He also remembered his brother River Phoenix, who died of a drug overdose at the age of 23 in 1993.

[We have to] continue to use our voice for the voiceless. I've been thinking a lot about some of the distressing issues that we are facing collectively. I think at times we feel, or were made to feel, that we champion different causes, but for me, I see commonality. I think, whether we're talking about gender inequality or racism or queer rights or indigenous rights or animal rights, we're talking about the fight against injustice. We're talking about the fight against the belief that one nation, one people, one race, one gender or one species has the right to dominate, control and use and exploit another with impunity.

I think that we've become very disconnected from the natural world, and many of us, what we're guilty of is an egocentric worldview — the belief that we're the center of the universe. We go into the natural world, and we plunder it for its resources. We feel entitled to artificially inseminate a cow, and when she gives birth, we steal her baby, even though her cries of anguish are unmistakable. Then, we take her milk, that's intended for her calf, and we put it in our coffee and our cereal, and I think we fear the idea of personal change because we think that we have to sacrifice something to give something up. But human beings, at our best, are so inventive and creative and ingenious, and I think that when we use love and compassion as our guiding principles, we can create, develop and implement systems of change that are beneficial to all sentient beings and to the environment.

Now, I have been a scoundrel in my life. I've been selfish. I've been cruel at times, hard to work with and ungrateful, but so many of you in this room have given me a second chance. And I think that's when we're at our best, when we support each other, not when we cancel each other out for past mistakes, but when we help each other to grow, when we educate each other, when we guide each other toward redemption. That is the best of community.

When he was 17, my brother wrote this lyric. It said, 'Run to the rescue with love, and peace will follow.'"
