Michael Mann is developing Heat 2, which serves as both a prequel and sequel, and that has led to speculation over which actor should be cast as young Vincent Hanna. Featuring the titanic on-screen pairing of Robert De Niro and Al Pacino, the original Heat gave audiences a gripping narrative focused on the cat-and-mouse game between a seasoned criminal, Neil McCauley (De Niro), and LAPD detective Vincent Hanna (Pacino). Beyond its intricate plot, Heat is lauded for its visceral heist sequences and the electric dynamic between its two leads, forever securing a place as an action classic. Years after its release, Mann co-wrote the novel Heat 2 with Meg Gardiner.
