Leonardo DiCaprio and Tom Hardy may be on-screen enemies in The Revenant, but they will join together on the red carpet for the film's UK premiere.
The movie, which is inspired by true events, is an epic story of survival on the American frontier. DiCaprio plays legendary explorer Hugh Glass, who is brutally mauled by a bear and left for dead by his own hunting team.
This is the start of a brutal 200-mile odyssey through the American West, on the trail of the man who betrayed him, John Fitzgerald (Tom Hardy).
It is the second time DiCaprio and Hardy have co-starred in a film, after 2010's Inception.
Others confirmed to attend include stars Domhnall Gleeson and Will Poulter, and director Alejandro Gonzalez Inarritu.
The premiere will take place just a few hours after the Oscar nominations are announced, with the film - and its star DiCaprio - widely expected to pick up nods in several categories.
DiCaprio has never won an Oscar before despite four nominations, but he will be hoping this is finally his year.
The film has already won three Golden Globes, and is nominated for Bafta Film Awards in eight categories - including Best Actor, where DiCaprio will face competition from Eddie Redmayne, Michael Fassbender, Matt Damon and Bryan Cranston.
