She seemed to be in incredible high spirits as she posed up a storm with acting legend Robert, who wrapped up warm in a smart black trench coat layered with a grey scarf. 

At times adapting a documentary film-style approach, The Alto Knights recounts the old friends’ shared past, the events leading to their rift and a failed ᴀssᴀssination attempt on Costello. 

Their power struggle plays out in tense scenes, some of which see Costello and Genovese clash face to face. 

The movie is directed by Rain Man, Good Morning, Vietnam and Wag the Dog filmmaker Barry Levinson and written by Nicholas Pileggi, known for Goodfellas and Casino.

It is produced by De Niro’s long-time collaborator Irwin Winkler, and the actor said working with the trio convinced him to return to the mobster genre.

‘I wasn’t planning on going back to it, but when Irwin Winkler sent me the script, I said ‘let me consider,’ De Niro said at the film’s London premiere on Thursday.

‘When we were talking about who’d play the other part, they wanted me for Costello, he (Winkler) said ‘well, what about if you play the other part?’ I said ‘that’s an even better reason to do this, if I do it,’ the 81-year-old actor added.

Winkler, 93, said he couldn’t think of anyone else better suited for the roles.

‘We didn’t do it with any visual effects. It was all really makeup and just him,’ Winkler said. ‘Even after seeing the film so many times, I see two different characters. I don’t see one man playing them.’

De Niro enlisted a co-star to act out scenes featuring both of his characters.

‘I settled on one guy I thought would be good. He played the Gambino part and he learned both parts. So, I did it with him and he was a tremendous help.’

As well as Debra playing Costello’s wife, Shogun actor Cosmo Jarvis portrays gangster Vincent Gigante. 

Asked if the experience had inspired him to challenge himself further, De Niro, who has several new film projects lined up, said: ‘Now I’m just trying to keep up with everything I’m doing.’

It comes after Debra and Melanie Lynskey were shocked to discover they had famous — if distant — relatives on an episode of Finding Your Roots last month.

Debra learned that she was related to a famous American politician and former presidential candidate, while Melanie, 47, was ecstatic after finding out that she shared a small connection to an influential musician.

In fact, both distant cousins had previously appeared on the PBS series, the host, Henry Louis Gates Jr., revealed.

Toward the end of the episode, Debra was aghast to learn that she is related to Vermont’s independent United States senator, Bernie Sanders.

The 83-year-old politician, who is the longest serving independent in congressional history, previously ran for president in the 2016 and 2020 cycles while seeking the Democratic nomination.

‘What! Are you kidding me? Bernie Sanders?’ Debra reacted after learning that she shared some key portions of her DNA with the senator, via People. ‘No way! Oh my gosh… That is mind-blowing.’
