Robert De Niro films Netflix series Zero Day in NYC in blazer with American flag pin ... after urging fans not to vote for 'total monster' Donald Trump in this fall's presidential election

Robert De Niro was pictured working on the limited Netflix series Zero Day in his native New York City on Tuesday.

The two-time Academy Award winner, 80, was clad in a navy blue blazer over a button-up blue checkered shirt with a navy blue tie with diagonal stripes, as he toted files in his hand.

De Niro, who welcomed daughter Gia Virginia last year with his girlfriend, martial arts instructor Tiffany Chen, 45, rounded out his ensemble with khaki pants and eyeglasses with black frames.

The actor plays the role of former President George Mullen in the limited six-episode series, in which his costars include Angela Bassett, Jesse Plemons, Connie Britton, Gaby Hoffmann, Lizzy Caplan and Matthew Modine, the streaming service said in December.

A logline for the series reads, 'Zero Day asks the question on everyone’s mind: How do we find truth in a world in crisis, one seemingly being torn apart by forces outside our control? And in an era rife with conspiracy theory and subterfuge, how much of those forces are products of our own doing, perhaps even of our own imagining?'

De Niro last month was nominated for Best Supporting Actor for his performance as William Hale in Killers of the Flower Moon, but lost out on the honors to Robert Downey Jr.

De Niro has past won Oscars for his work in 1974's The Godfather Part II and 1980's Raging Bull, and has also been nominated for his work in The Irishman, Silver Linings Playbook, Cape Fear, Awakenings, The Deer Hunter and Taxi Driver.

Among his other notable non-nominated performances in cinema include Goodfellas, The King of Comedy, The Untouchables and A Bronx Tale.

The actor has historically been outspoken about political issues he holds dear, and  vocal in recent years about presumptive Republicans presidential candidate and former President Donald Trump.

Appearing last month on Real Time with Bill Maher, De Niro said that the 2024 presidential election presents potential extreme results for voters.

'We wanna live in a world that we want to live in and enjoy living in, or live in a nightmare?' De Niro said. 'Vote for Trump and you'll get the nightmare, vote for Biden and we'll be back to normalcy.

'I just don't want to feel the way I did the many months after the election in 2016, where we couldn't believe that it happened.'

De Niro condemned Trump as a 'total monster' and 'a mean, nasty, hateful person.'

Trump was snapped during the LIV Golf Miami Tournament on April 7 in Doral, Florida 

He said he doesn't understand how the controversial TV personality-turned-politician maintains loyalty from his base.

'I don't understand it, I guess they get behind that kind of logic they wanna f*** with people, screw them because they're unhappy about something,' he said.

And despite a resume of roles spanning questionable fictional characters such as Travis Bickle and Max Cady, as well as late fraud kingpin Bernie Madoff, De Niro said he'd 'never' be up to the task of playing Trump, as he 'can't see any good in him' whatsoever.

De Niro added, 'Nothing, nothing at all, nothing redeemable.'

De Niro added of President Joe Biden: 'The bottom line is Biden's our guy. He represents what this country's supposed to be about.'

In the chat with Maher, the iconic actor said that he doesn't mind have a packed schedule at 80.

'I'm very busy - I enjoy it - I don't mind it,' De Niro said. 'I keep going because I know if you don't keep going, you're gonna atrophy and you're gonna dry up and I don't wanna do that. So I'm just trying to keep as busy as I can.'

De Niro's iMDb page lists six current projects he's working on, in different stages of production. They include the films Tin Soldier, Alto Knights and After Exile, the TV projects Zero Day and Mr. Natural, and an untitled project.
