Al Pacino and Robert De Niro have been confirmed to appear together in a new film, according to Variety.

The film, Righteous Kill, will be only the second time that the two legendary actors have appeared on-screen together.

They shared two scenes together in 1995's Heat and although both were in The Godfather: Part II, they never appeared in the same scene.

Righteous Kill, however, will see De Niro and Pacino perform together throughout.

Producer Randall Emmett said: "They're friends, and this really all got started from that."

The film's co-producer said categorically: "This is an event in world history."
