They're bringing gangster back as they collaborate for 2019-scheduled Netflix movie The Irishman.
And old pals Robert De Niro and Al Pacino looked beyond thrilled to have reunited, alongside director Martin Scorsese whom De Niro has worked with on mob projects in the past.
The film is based on real-life hitman Frank 'The Irishman' Sheeran - written about in the book I Heard You Paint Houses.

De Niro and Pacino were seen shooting the scenes outside a New York property, appearing to have a tiff outside on the porch.
Scorsese waded onto the front lawn in a straw hat to give direction, with De Niro fiddling with the head-wear, leaving the old friends and colleagues chuckling with each other.
On Monday crews were spotted on New York's Randall's Island filming an assassination scene for the mob movie but none of the stars seemed to be present.
It was recently revealed that De Niro will earn $775,000 per episode of an upcoming Untitled David O. Russell TV project for Netflix's rival Amazon, according to Variety.

Scorsese was attached to direct The Irishman from as far back as 2014 when Pacino confirmed that the film was in development.
He said that it would be Scorsese's next project after Silence.
Originally, the movie was looking to shoot in 2016 with Steve Zaillian penning the adaptation, but it was pushed back.
In May 2016, it was announced that the film's rights would be offered at the 2016 Cannes Film Festival, while Mexican producer Fábrica de Cine had offered $100 million to finance the film.

He later dropped out thanks to the movie's constantly climbing budget which led to the distributing company, Paramount, dropping their involvement.
Netflix then bought the film for $105 million and agreed to finance the film's hefty $125 million budget with a release date set for next year.
It's rumoured that Pesci turned down the offer to be in the movie 50 times before agreeing to take part.
The movie is set to wrap filming in December 2017.
