It sounds like an instant classic: a mob movie with Robert De Niro, Al Pacino and Joe Pesci, helmed by none other than Martin Scorsese.

De Niro confirmed the new project, also dubbed "The Irishman," in a report from Digital Spy. While promoting his film "The Intern," the A-list actor took the time to talk about his latest collaboration with his favorite director.

"We are doing it... We should be doing it sometime next year," De Niro confirmed. "We're slowly, slowly getting it in place."

This upcoming mob movie is based on Charlie Brandt's best-selling novel "I Heard You Paint Houses: The Story Of The Biggest Mob Hit In History." The story revolves around Frank "The Irishman" Sheeran, a hitman who rose to prominence after working with crime boss Russell Bufalino. Sheeran narrated his story to Brandt over the course of five years, which includes twenty-five hits for the mob.

De Niro revealed more about this project in an interview at "The Tonight Show with Jimmy Fallon" expressing his excitement at the new movie, according to a report from Digital Spy.

"We have been trying to do [the film] for the last few years, and I think we will do it," he told Fallon during the talk show. "It's about a guy who... confessed that he killed [Jimmy] Hoffa and [infamous New York gangster] Joe Gallo."

"I'm gonna play that character," he continued. "That's something I'm looking forward to very much."

The upcoming film will reunite with the acclaimed director after working together in several films including "Goodfellas," "Taxi Driver," "Cape Fear," "Raging Bull," "Casino" and "Mean Streets."

The movie has long been in the works, the project going as far back as 2010 when De Niro first began talking about it. In an interview with MTV, the actor revealed that they are planning something that could potentially stretch to two films with a meta-type concept.

"We have a more ambitious idea, hopefully, to make it a two-part type of film or two films," he said. "It's an idea that came about from Eric Roth to combine these movies using the footage from 'Paint Houses' to do another kind of a [film that is] reminiscent of a kind of '8 1/2,' 'La Dolce Vita,' [a] certain kind of biographical, semi-biographical type of Hollywood movie - a director and the actor - based on things Marty and I have experienced and kind of overlapping them."

There has been no confirmation of the two-part movie since then.
