Tom Hardy is officially set to join Leonardo DiCaprio in New Regency’s Western “The Revenant.”

Hardy had been linked to the project for several weeks but needed to work out his very busy schedule before fully committing.

The duo last worked together on Christopher Nolan’s “Inception.”

Will Poulter (“We’re the Millers”) is also in negotiations to join the cast of the drama with Alejandro González Iñárritu directing.

Pic will shoot this fall.

Based on the Michael Punke novel, “The Revenant” centers on a 1820s frontiersman on a path of vengeance against those who left him for dead after a bear mauling. Mark L. Smith and Inarritu penned the adaptation.

Anonymous Content’s Steve Golin, Keith Redmon and David Kanter will produce along with Inarritu, Arnon Milchan and James Skotchdopole. New Regency is co-financing the film with RatPac.

Paul Green, Brett Ratner and James Packer are exec producing.

Hardy was most recently seen in the Steven Knight’s acclaimed indie “Locke.” He is repped by CAA, Lindy King at United Agents and attorney Jason Sloane of Sloane Offer Weber & Dern.
