EDITOR'S NOTE: Jake Gyllenhaal Being Courted To Replace Hardy In "Suicide Squad"

Tom Hardy, who was announced in December as part of Warner Bros' all-star cast for its DC Comics-based "Suicide Squad" movie, has reportedly dropped out of the project.

The news arrives courtesy of The Hollywood Reporter, which states the reasons for Hardy's departure aren't immediately clear. However, his involvement in Alejandro Gonzalez Inarritu's frontier drama "The Revenant," whose shoot appears to be running longer than planned, seems a likely candidate.

Hardy would have played Rick Flag, leader of the Suicide Squad, in David Ayer's adaptation, which the director has described as the "'Dirty Dozen' with supervillains,"

With Hardy's exit from the project, that leaves Jared Leto as the Joker, Will Smith as Deadshot, Margot Robbie as Harley Quinn, Jai Courtney as Boomerang and Cara Delevigne as Harley Quinn. Viola Davis is reportedly nearing a multi-picture deal to play Amanda Waller.

Hardy will next be seen in Warner Bros.' "Mad Max: Fury Road."

Set to begin filming in mid-April in Toronto, "Suicide Squad" opens Aug. 5, 2016.
