Martin Scorsese’s The Irishman has been in the works for years, and while Al Pacino and Robert De Niro have both said in the past that they’re involved, it’s been ages since any additional news about the project has come out. But on Tuesday’s episode of The Tonight Show, host Jimmy Fallon asked De Niro about the Irishman rumors — and the actor said it’s still happening.

Based on Charles Brandt’s true-crime book I Heard You Paint Houses, The Irishman focuses on a mafia hitman named Frank Sheeran, who’s rumored to be involved with the assassinations of John F. Kennedy and Jimmy Hoffa. De Niro told Fallon that Pacino and Joe Pesci are involved with the project, with Scorsese directing and Harvey Keitel “maybe” joining the cast.

Check out the clip below to hear Robert De Niro talk further about The Irishman (and to watch Fallon geek out over the thought of Pacino, De Niro, and Pesci on screen together in a Scorsese pic).
