In pictures: Memorable Oscars speeches from past Academy Award winners

From Will Smith’s vague apology to Michael Moore berating George Bush, ahead of the 93rd Academy Awards this weekend, let's take a look back at some of the most memorable Oscars speeches from throughout the years.

After delivering an open-handed slap to Chris Rock, Will Smith made a vague apology during his acceptance speech "Richard Williams was a fierce defender of his family. Art imitates life … love will make you do crazy things,” - Best actor winner Will Smith for King Richard, 2022.

"Before the world tonight, I give praise to our ancestors who helped build this country [unintelligible] today, along with the genocide of its native people. We all connect with our ancestors. We will have love, wisdom regained, we will regain our humanity. It will be a powerful moment. The 2020 presidential election is around the corner. Let's all mobilize. Let's all be on the right side of history. Make the moral choice between love versus hate. Let's do the right thing!" - Best adapted screenplay winner Spike Lee, with Charlie Wachtel, David Robinowitz and Kevin Willmott, for Blackkklansman, 2019

"Marvel may have created the first black superhero, but through costume design we turned him into an African king. It's been my life's honor to create costumes." - Best costume design winner Ruth E. Carter for Black Panther, 2019.

"Making The Revenant was about man's relationship to the natural world. A world that we collectively felt in 2015 as the hottest year in recorded history. Our production needed to move to the southern tip of this planet just to be able to find snow. Climate change is real, it is happening right now. It is the most urgent threat facing our entire species, and we need to work collectively together and stop procrastinating. We need to support leaders around the world who do not speak for the big polluters, but who speak for all of humanity, for the indigenous people of the world, for the billions and billions of underprivileged people out there who would be most affected by this. For our children's children, and for those people out there whose voices have been drowned out by the politics of greed. I thank you all for this amazing award tonight. Let us not take this planet for granted." - Best actor Leonardo DiCaprio for The Revenant, 2016.

"I am the king of the world." - Best director James Cameron for Titanic, 1998.

"Look around, ladies and gentlemen, because we all have stories to tell and projects we need financed. Don't talk to us about it at the parties tonight. Invite us into your office in a couple days--or you can come to ours, whichever suits you best--and we'll tell you all about them. I have two words to leave with you tonight, ladies and gentlemen: inclusion rider." - Best actress Frances McDormand for Three Billboards Outside Ebbing, Missouri, 2018.

"When I look down at this golden statue, may it remind me and every little child that no matter where you're from, your dreams are valid." - Best supporting actress Lupita Nyong'o for 12 Years a Slave, 2014.

"I'd be lying if I hadn't made a version of this speech before, I think I was probably eight years old and staring into the bathroom mirror. And this would've been a shampoo bottle. Well, it's not a shampoo bottle now!" - Best actress Kate Winslet for The Reader, 2009.

"I am an immigrant like Alfonso and Alejandro, my compadres. Like Gael. Like Salma. And like many, many of you. And in the last twenty-five years, I've been living in a country all of our own: part of it is here, part of it is in Europe, part of it is everywhere. Because I think that the greatest thing our art does and our industry does is to erase the lines in the sand. We should continue doing that when the world tells us to make them deeper." - Best director Guillermo del Toro for The Shape of Water, 2018.

"There's one place that all the people with the greatest potential are gathered. One place. And that's the graveyard. People ask me all the time, 'What kind of stories do you want to tell, Viola?' And I say, exhume those bodies. Exhume those stories. The stories of the people who dreamed big and never saw those dreams to fruition. People who fell in love and lost. I became an artist, and thank god I did, because we are the only profession that celebrates what it means to live a life. So here's to August Wilson, who exhumed and exalted the ordinary people." - Best supporting actress Viola Davis for Fences, 2017.

"We made this film for all the journalists who have and continue to hold the powerful accountable, and for the survivors whose courage and will to overcome is really an inspiration.

"I know that my work in this case is magnified by the fact that the streets of heaven are too crowded with angels. We know their names. They number a thousand for each one of the red ribbons that we wear here tonight. They finally rest in the warm embrace of the gracious creator of us all. A healing embrace that cools their fevers, that clears their skin, and allows their eyes to see the simple, self-evident, common sense truth that is made manifest by the benevolent creator of us all and was written down on paper by wise men, tolerant men, in the city of Philadelphia 200 years ago." - Best actor Tom Hanks for Philadelphia, 1994.

"I want to thank Brandon Teena for being such an inspiration to us all. His legacy lives on through our movie to remind us to always be ourselves, to follow our hearts, to not conform. I pray for the day when we not only accept our differences, but we actually celebrate our diversity." - Best actress Hilary Swank for Boys Don't Cry, 2000.

"We live in a time when we have a man sending us to war for fictitious reasons. We are against this war, Mr. Bush. Shame on you. Shame on you!" - Best documentary feature winner Michael Moore for Bowling for Columbine, 2003.

I promise you do. You do. Stay weird. Stay different. And then when it's your turn and you are standing on this stage, please pass the same message to the next person who comes along." - Best adapted screenplay writer Graham Moore for The Imitation Game, 2015.

"To the audiences who went to see it, and perhaps those of us in the industry who are still foolishly clinging to the idea that female films with women at the center are niche experiences. They are not. Audiences want to see them and, in fact, they earn money. So... The world is round, people!" - Best actress Cate Blanchett for Blue Jasmine, 2014.

"When they called my name, I had this feeling I could hear half of America going, 'Oh no. Come on... Her, again?' You know. But, whatever." - Best actress Meryl Streep for The Iron Lady, 2012.

"Did I really earn this, or did I just wear you all down?" - Best actress Sandra Bullock for The Blind Side, 2010.
