EXCLUSIVE: It’s been nearly three decades since Michael Mann’s crime classic hit theaters and it now feels like Mann and Warner Bros. are finally feeling more heat around the corner for a sequel to Heat. While rumors have been swirling for weeks, Deadline is hearing Warner Bros. is now in negotiations to come on to develop Heat 2, the sequel to the 1995 classic that Mann recently turned into a novel that became a New York Time #1 best-seller when it was published last August. On top of Warner Bros. in talks to return, insiders add that Adam Driver, who recently starred in Mann’s Ferrari pic, is in discussions with Mann to play young Neil McCauley in the movie.
