The first Heat movie was released in 1995 and told the story of a cat-and-mouse game between an experienced detective and a resourceful bank robber, played by Al Pacino and Robert De Niro respectively.
Even before it was released it gained significant attention as it would be the first time that De Niro and Pacino appeared on-screen together. Indeed, one of the most famous scenes in the movie is a conversation between the pair in a cafe.
A sequel or prequel has been discussed for a while, and Mann eventually pulled the trigger with a novel, Heat 2.
It is both a sequel and a prequel, as the story features one narrative following the events of the first movie and one narrative before it focusing on younger versions of Neil McCauley and Vincent Hanna.
Mann's next movie will be an adaptation of his novel.
"Meg Gardiner and myself wrote the novel 'Heat 2', which came out right when we were shooting 'Ferrari'. It did very well. I plan to shoot that next," the director told Deadline.
Detective Vincent Hanna (Al Pacino) is obsessed with the thief Neil McCauley (Robert De Niro) and tries to catch him, if necessary, at the cost of his private life. As McCauley prepares for the heist of a lifetime, and Hanna's team tries to catch him, both realise they are dealing with the very best in their trade.
When the novel came out, fans speculated that Adam Driver would make an ideal casting choice for the role of young Neil McCauley, and those rumours only intensified when Driver and Mann worked together on Ferrari.
Mann was asked if Driver had been cast in Heat 2, but he played it coy.
"Perhaps. We don’t talk about that yet," he replied.
"Let me put it this way: Adam and I got along like a house on fire . We have the same work ethic – which is pretty intense. We like each other, and we had a great time working together artistically.”
