Mann has long been working hard to deliver a sequel to his 1995 crime thriller, and with a novelization published and public interest sufficiently stoked, the director has spent the past few years pushing for a big-screen adaptation. The script for Heat 2 is complete, but needs help getting past the development stage. Warner Bros.Puck reports that Warner Bros. is apparently pushing back against Mann’s projected budget, which initially stood at a whopping $200 million. It’s not clear who DiCaprio would play, as Heat 2 serves as both a prequel and a sequel to the original film. But he’s a bankable star, and his involvement could go a long way to cultivating the buzz this film needs.
