This is the first time the majority of the Sopranos cast has reunited since last year’s 20th-anniversary celebrations.
The beloved HBO flagship drama ran for six seasons, from 1999 to 2007, and won 21 Emmys, including two for Best Drama Series.
Next year, a Sopranos prequel film, The Many Saints of Newark, is set to open on 12 March. Directed by Alan Taylor and written by Chase, The Many Saints of Newark stars Michael Gandolfini, son of late Sopranos star James Gandolfini, as a young Tony Soprano coming of age in the organized crime arena. James Gandolfini, who starred as mobster Tony Soprano, died in Rome in 2013 aged 51.
The film also stars Alessandro Nivola, Leslie Odom Jr. Jon Bernthal, Corey Stoll, Billy Magnussen, John Magaro, Michela De Rossi, Ray Liotta and Vera Farmiga.
