Righteous Kill by Dirty Harry Robert De Niro and Al Pacino both starred in The Godfather II (1974) but were never on screen together (De Niro appeared as Pacino’s father in flashbacks); they also co-starred in Michael Mann’s Heat (1995), but only shared a couple of scenes

They shared a lot more than a "few scenes" in Heat.

“They shared a lot more than a “few scenes” in Heat.”

Agreed. Also a damned good movie.

Yep, watch that if you want a good De Niro/Pacino movie.
