The veteran actor made the announcement in an interview with his grandson Dylan Redford for the Walker Art Center, where he will appear at an event on 12 November (16).

"Once they’re done then I’m going to say, 'OK, that’s goodbye to all that,' and then just focus on directing," he said.

When asked if he would return to painting, the actor replied, "Yeah, a lot - and a lot lately because I’m getting tired of acting... I’m an impatient person, so it’s hard for me to sit around and do take after take after take. At this point in my life, age 80, it’d give me more satisfaction because I’m not dependent on anybody.

"It’s just me, just the way it used to be, and so going back to sketching - that’s sort of where my head is right now... So, I’m thinking of moving in that direction and not acting as much."

Robert has two acting projects in the pipeline including a love story for older people called Our Souls at Night with Jane Fonda and a lighter piece with Casey Affleck and Sissy Spacek called The Old Man and the Gun.

The veteran actor first directed in 1980 with Ordinary People, which won him a Best Director Oscar, and he last stepped behind the camera for 2012's The Company You Keep.

He also founded the Sundance Institute, which helps independent filmmakers and runs the annual Sundance Film Festival.

Robert studied art in Paris, France as well as at the Pratt Institute and American Academy of Dramatic Arts, both in New York, before pursuing acting.
