Robert Redford has revealed he embraced the loneliness of working on his new film All Is Lost.
The 77-year-old actor plays a man stranded on a yacht in the middle of the Indian Ocean in the film, written and directed by J C Chandor.
Robert admitted he especially enjoyed the quiet moments, when his character was just pottering about in the boat.
"In those moments of peace, he would just look out and contemplate what's there," he said. "He could see a vast expanse of nothing but space. And then underneath him on that small boat, just miles and miles of deep water. I can't imagine how you can feel more alone than that."
And the actor and director relished the chance to improvise on screen, all by himself.
"I saw it as an opportunity to do something I was longing to do - to have a complete experience as an actor and not think about anything else.
"I enjoyed the fact that it [All Is Lost] didn't have much information or dialogue, because it created a challenge for me to be more fully inside the character," he said.
"It also lets the audience have their own interpretation, instead of telling them how they are supposed to feel."
:: All Is Lost is in cinemas on December 26.
