Anora was the big winner at the Oscars, winning five awards including best actress for breakout star Mikey Madison, and a record-breaking four prizes for its director Sean Baker.
The whirlwind drama stars relative newcomer Madison as a New York stripper who falls in love with the son of a wealthy Russian.
She held off competition from Demi Moore, and described winning the best actress Oscar as a "dream come true".
Baker became the first person to personally win four Academy Awards for a single film - for directing, editing, writing and producing Anora.
Other winners on the night included Kieran Culkin, Adrien Brody and Zoe Saldaña, while Flow won best animated film and I'm Still Here took home the best international prize.
In her speech, 25-year-old Madison said: "This is very surreal. I grew up in Los Angeles but Hollywood always felt so far away from me, so to be here standing in this room today is really incredible."
She added: "I want to honour and recognise the sex worker community. I will continue to support and be an ally... the women I've had the privilege of meeting from that community has been one of the highlights of this entire incredible experience."
The best director trophy was presented by Quentin Tarantino, who previously cast Madison in a small role in his film Once Upon A Time In Hollywood.
Accepting the trophy from Tarantino, Baker told him: "If you didn't cast Mikey Madison... there'd be no Anora."
Baker went on to thank the Academy voters for "recognising a truly independent film", and used his best director speech to champion cinemas.
"Where did we fall in love with movies? At the movie theatres," Baker said. "Watching a film in a theatre with an audience is an experience.
"And at a time when the world can feel very divided, this is more important than ever, it's a communal experience you just don't get at home.
"Right now the theatre-going experience is under threat, independently owned theatres are struggling, and it's up to us to support them."
He concluded: "This is my battle cry: Film-makers, keep making films for the big screen. I know I will. Distributors, please focus first and foremost on the theatrical releases of my films."
Baker is the first person to win four Oscars for a single film. Walt Disney did win four prizes in a single night in 1953, but for four different films.
The Brutalist's Adrien Brody was named best actor for his performance as a Hungarian-Jewish architect who moves to the US after World War Two to build a new life.
Brody had not been nominated at the Oscars since 2003, when he became the youngest ever winner of best actor for The Pianist.
"Acting is a very fragile profession," he said. "It looks very glamorous, and in certain moments it is, but the one thing I've gained in having the privilege to come back here is to have some perspective.
"And no matter where you are in your career, no matter what you've accomplished, it can all go away. And what makes this night so special is the awareness of that, and the gratitude I have to still do the work that I love."
Brody refused to be played off during his five-minute speech, continuing: "I'm here once again to represent the lingering traumas and repercussions of war, and systematic oppression, and antisemitism and racism.
"And I pray for a healthier, happier and more inclusive world. And I believe if the past can teach us anything, it's a reminder to not let hate go unchecked."
The Brutalist also scored two British wins - best cinematography for Lol Crawley, who grew up in Wales, and best original score for composer Daniel Blumberg.
