The director, 83, is developing the project as an adaptation of his 2022 novel Heat 2, co-written with Meg Gardiner, which acts as both a prequel and sequel to Heat. The story spans multiple timelines - from late-1980s Chicago to post-heist Los Angeles in the 1990s and into the early 2000s - and revisits key characters originally portrayed by Al Pacino, Robert De Niro and Val Kilmer, who died at age 65 in 2025.
