Fox has debuted a new trailer for "The Revenant," the Western thriller starring Leonardo DiCaprio and Tom Hardy.

Directed and co-written by Alejandro G. Iñárritu ("Birdman"), the film follows an early 19th-century expedition of the American wilderness, where explorer Hugh Glass (DiCaprio) is mauled by a bear, and then robbed and left for dead by his own hunting companions. Defying the odds, Glass survives, and sets out on a 200-mile journey to exact revenge against the men who betrayed him.

Inspired by actual events, "The Revenant" also stars Will Poulter, Domhnall Gleeson and Lukas Haas. The film opens Dec. 25.
