"Robert asked me to call him Bob which I thought was awesome," the Mirror quoted her as saying. "I was like,'Yes, I'm one of the few people that get to call Mr De Niro Bob,so I feel super cool," she said.
In 'Stone", De Niro plays a hardened parole officer who is confronted by the young wife (Milla) of convicted arsonist Gerald Creeson (Edward Norton) during a parole review.
"I think he was a little intimidated by me," she said about her first meeting with De Niro. And the actress revealed he had a profound effect on her acting.
"It was such an amazing experience to work in a way that is so organic and natural that it really doesn't matter what a script says when somebody is trying to find something real and you''ve gotta help them do it," she said.
"It was a great learning experience for me as an actress," she added.
