Leonardo DiCaprio is feeling the heat - over Heat 2, with sources telling OK! the 51-year-old actor is under "intense pressure" as he edges toward what will be one of the most physically demanding roles of his career.

The long-awaited sequel to Michael Mann's 1995 classic Heat is finally moving forward, with the 82-year-old director set to return and DiCaprio set to play gun-toting gangster Chris Shiherlis, originally portrayed by Val Kilmer.

While no contract has been signed, industry sources say DiCaprio is "definitely" Mann's preferred choice for the part, and will "100 percent" be taking the role.

The project draws heavily from Mann's bestselling novel Heat 2, which serves as both a prequel and sequel to his 1995 film. The book follows Shiherlis and Al Pacino's hardened detective Vincent Hanna through intersecting timelines, tracking Hanna's early career in the 1980s and his later pursuit of an on-the-run Shiherlis. Mann's narrative also introduces a new antagonist, the violent criminal Otis Wardell.

But it is DiCaprio's attachment that has generated the most attention so far, particularly as the actor continues to pivot toward more physically challenging work after recent comedy-drama projects such as One Battle After Another.

For Mann, whose reputation for precision on and off set remains virtually unmatched in Hollywood, authenticity is non-negotiable. In Heat 2, the character of Shiherlis will be central to the story's emotional and psychological through-line, making the casting choice "particularly impactful," according to sources.

Industry watchers note DiCaprio has not taken on a pure action role in years, and the physicality required for Shiherlis - from firefights to high-intensity escape sequences - marks a shift from his recent dramatic work. One production source said: "Leo preparing for the reality that this won't be easy, especially now he is in his 50s. Mann's sets are famously demanding, and that's before you add the legacy of Heat."The structure of the Heat 2 novel, weaving between decades and locations, has also increased excitement among potential cast members. Production sources say audiences are hungry for adult blockbusters, with recent titles such as Weapons and Sinners showing strong appetite for non-franchise, auteur-led films.

One insider said: "Leo is definitely set to do it - but he wants to get it right. That's why he's literally feeling the heat."
