Actress Emma Stone has recently come under a lot of scrutiny over her role in the recent 'Aloha' film in which she plays an Air Force pilot whose father was half-Hawaiian and half-Chinese.

She has since come out about the controversy and her recent enlightenment on the whitewashing in Hollywood in an interview with News.com.au.

"I've learned on a macro level about the insane history of whitewashing in Hollywood and how prevalent the problem truly is. It's ignited a conversation that's very important," she admits.

In the director's defense, she claims the character was to be based on a real-life person he had encountered.

"I am grateful for the dialogue. And from the many voices, loud and small, I have learned something very inspiring," Crowe wrote in a blog post. "So many of us are hungry for stories with more racial diversity, more truth in representation, and I am anxious to help tell those stories in the future."

Stone's casting in the movie evidently wasn't only criticized for her portrayal as an Asian American, but her typecasting with older romances.

"It's rampant in Hollywood and it's definitely been that way for a long time, both culturally and in movies. But in Irrational Man, the film is contingent upon the age difference; the movie is about that disparity. And when I did Magic in the Moonlight Colin Firth and I talked about the gap which was huge, absolutely, because he was born the same year as my dad," she says.

"There's a lot of conversation about how we want to see people represented on screen and what we need to change as a business to reflect culture in a clearer way and not in an idealised way," she continues. "There are some flaws in the system. My eyes have been opened in many ways this year."
