Halle Berry thought she paved the way for diversity at the 2001 Academy Awards.

Speaking about the controversy surrounding this year's ceremony because of the lack of black actors nominated in any of the categories, she said: "I believed that in that moment, that when I said [in my acceptance speech], 'The door tonight has been opened,' I believed that with every bone in my body that this was going to incite change because this door, this barrier, had been broken.

"And to sit here almost 15 years later, and knowing that another woman of colour has not walked through that door, is heartbreaking. It's heartbreaking because I thought that moment was bigger than me. It's heartbreaking to start to think maybe it wasn't bigger than me. Maybe it wasn't. And I so desperately felt like it was."

The 49-year-old actress also insisted actors and filmmakers have a "responsibility" to look at the wider picture and not forget the "importance and the involvement" of people from all races and backgrounds in making history and being a part of American culture today.

Speaking at the 2016 Makers Conference, she added: "It's really about truth telling. And as filmmakers and as actors, we have a responsibility to tell the truth. And the films, I think, that are coming out of Hollywood aren't truthful.

"The reason they're not truthful, these days, is that they're not really depicting the importance and the involvement and the participation of people of colour in our American culture."
