Aishwarya starrer Jazbaa's first look launched at Cannes 2015

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.

"When he was 17, my brother wrote this lyric. He said, 'run to the rescue with love and peace will follow'," Phoenix said. At the Academy Awards and the entire Hollywood award season, Phoenix had emerged as an undisputed frontrunner even though he was up against the likes of Leonardo DiCaprio ("Once Upon a Time in Hollywood"), Adam Driver ("Marriage Story"), "Antonio Banderas ("Pain & Glory") and Jonathan Pryce ("The Two Popes").

An Oscar had eluded Phoenix for the most part of his career, despite his successful collaborations with Ridley Scott ("Gladiator"), James Mangold ("Walk The Line") and Paul Thomas Anderson ("The Master"), all of which had earned him nominations.

But as Arthur Fleck aka The Joker, Phoenix finally managed to break that jinx and became the second actor to win an Oscar for playing the DC comic book villain after the posthumous best supporting actor win to Heath Ledger in 2008.

As Joker, Phoenix took a deep dive into character, capturing its essence as well as maniacal spirit in both body and soul.

He lost 52 pounds to get into the physicality of Fleck and turned to a pathological disorder to get his distinct laughter right.

Phillips wrote the part keeping Phoenix in mind though the actor took some convincing to play the role.

Phoenix started the film's festival circuit tour on a positive note at Cannes last year that followed by stops at Venice and Toronto.

The film had also courted controversies, owing to its theme of gun violence in the movie as well as Phoenix's temperamental press tour that saw him walking out of an interview midway.

But critics and the fans loved the actor's riveting turn in the movie and his pointed speeches.

At the Golden Globes, he called out the industry for its insensitivity towards climate change and pulled up his peers for using private jets for travel, while at the SAGs, he joked how he would always lose a role to DiCaprio and asked Christian Bale to deliver a bad performance for once in his career.

In his acceptance speech at the BAFTAs, Phoenix acknowledged the lack of diversity in the nominations, calling himself a part of the problem. Phoenix's career most praised performances include "Signs ", "We Own the Night", "Two Lovers", "The Immigrant", "Her", "You Were Never Really Here" and "Inherent Vice".

London, Feb 12: Oscar-winning British director Steve McQueen is returning to his art roots with a series of short films at London's Tate Modern art gallery, offering a sensory exploration of black identity.

McQueen, who became the first black director to win the best picture Academy Award in 2014 for "12 Years a Slave", is now based between London and Amsterdam and is focused on championing diversity in the film industry.

Visitors to his new exhibition will be greeted by "Static", a film of New York's Statue of Liberty, scrutinising the iconic symbol from every possible angle at very close range against a deafening backdrop of the helicopter from where the footage was filmed.

"What interests Steve is our view of the world, how humans are trying to represent Liberty," said Fiontan Moran, assistant curator of the exhibition.

"7th Nov, 2001" features a still shot of a body while McQueen's cousin Marcus tells of how he accidentally killed his brother, a particularly traumatic experience for the artist.

"Western Deep" is another visceral work, giving a sense through sights and sounds in an interactive installation of the experiences of miners in South Africa, following them to the bottom of the mine.

"Ashes", meanwhile, is a tribute to a young fisherman from Grenada, the island where McQueen's family originated.

The images of beauty and sweetness filmed from his boat are tragically reversed on the other side of the projection screen, which shows a grave commissioned by McQueen for the eponymous young fisherman, who was killed by drug traffickers.

African-American singer, actor and civil rights activist Paul Robeson (1898-1976) is honoured in "End Credits".

The film shows censored FBI documents detailing the agency's surveillance of Robeson, read by a voice-over artist, for five hours.

"He is... testing the limits of how people can be documented in an era of mass surveillance," said Moran.

In a similarly militant vein, the exhibition features the sculpture "Weight", which was first shown in the prison cell where the writer and playwright Oscar Wilde was imprisoned.

It depicts a golden mosquito net draped over a metal prison bed frame, addressing the theme of confinement and the power of the imagination to break free.

The show runs alongside an exhibition of McQueen's giant portraits of London school classes, many of which appeared on the streets of London last year.

"I remember my first school trip to Tate when I was an impressionable eight-year-old, which was really the moment I gained an understanding that anything is possible," said McQueen, adding it was "where in some ways my journey as an artist first began".

He recently told the Financial Times newspaper the difference between his art films and his feature films was that the former were poetry, the latter like a novel.

"Poetry is condensed, precise, fragmented," he said. "The novel is the yarn".

The exhibition opens on February 13 and runs until May 11.
