Halle Berry became the first woman of colour to win the best actress Oscar in 2002, but the actress is "profoundly hurt" as no other women of colour have taken home the statuette for that category till now.
The 50-year-old actress, who won the award for her performance in "Monster's Ball", said the achievement of becoming the first black woman to win the best actress Oscar was made to feel worthless by the subsequent lack of diversity, reported People magazine.
"It's troubling, to say the least. It was probably one of my lowest professional moments because I sat there and I remembered that speech. I sat there and I thought, 'Wow that moment really meant nothing'.
"I was profoundly hurt by that and saddened by that and it inspired me to try to get involved in other ways, which is why I want to start directing, I want to start producing more, I want to start being a part of making more opportunities for people of colour," Berry told Teen Vogue.
She also said she had spoken to the Academy Award organisers to boost diversity within those who decide winners.
The focus should also be on getting more non-white people to produce and direct films, not just star in them, she added.
