Zelda Williams opens up about late father Robin Williams' death

For the first time, the daughter of late actor Robin Williams is opening up publicly about her father's death.

Zelda Williams sat down with NBC's "Today" show and covered a range of topics regarding her late father, talking about how the world saw him, his private life and his suicide.

"It's not to say people didn't know Dad. They knew a dad that he was proud of them knowing," Williams said.

"There's often that 'why did this happen' question," NBC reporter Kate Snow said.

"I don't think there's a point. ... It's not important to ask because it's ..." Williams said.

"It's done," Snow said.

In Zelda's interview, which aired Thursday, she also called her father a private, calm and subdued man when not in the public spotlight.

Robin Williams committed suicide Aug. 11 last year after reportedly suffering from depression for years.

A day after Williams' death, Zelda released a statement saying, in part, "There are few things I know for certain right now, one of them is that not just my world, but the entire world is forever a little darker, less colorful and less full of laughter in his absence."

"You know, it's taking it one step at a time. The world keeps spinning," she told NBC.

Zelda also talked about the Challenged Athlete Foundation, a charity Williams would often compete in triathlons for that helps provide prosthetic limbs for disabled athletes.
