Birth of a Nation director Nate Parker has issued an apology for "tone deaf" remarks he made three years ago after reports of him allegedly raping a woman back in college surfaced online.

"The last three years have been such a learning experience for me," he said at a press conference at the Venice Film Festival, per Variety. "I feel like I have gained so much wisdom from people in my circle," he added.

"Three years ago I was pretty tone-deaf to the realities of certain situations that were happening in the climate. And I've had a lot of time to think about that, and I've learned a lot from it," he said. "And being tone-deaf, there were a lot of people that were hurt in my response, in the way I approached things. I apologize to those people."

Parker's debut movie The Birth of a Nation, was bought by Fox Searchlight for a $17.5 million deal at Sundance but flopped at the box office because of a boycott over the rape allegations. 

Parker had been charged with rape as a college student, although he was acquitted in that case, in 2001, but his cold response to the news that his victim had been driven to commit suicide because of the assault sparked outrage.

"I've learned, I'm continuing to learn," he said Sunday. "I'm 39 years old now. Hopefully, I have a long way to go. The hope is that I can continue taking the wisdom from people who care enough…and help me to be introspective about where I am and what I've been through."

He is currently promoting his new movie, American Skin, which tackles police brutality.
