Jake Gyllenhaal will not be joining the cast of DC Comics movie Suicide Squad to replace Tom Hardy, following the British actor's recent exit.

Sources have told Variety that Gyllenhaal has turned down an offer to play supervillain Rick Flag, alongside Jared Leto as The Joker, Will Smith as Deadshot and Margot Robbie as Harley Quinn.

Producers need to find an actor to replace Hardy before April, when the film enters production.

And despite claiming that scheduling conflicts caused his exit, it's been reported that Hardy left due to problems with the script.

Suicide Squad follows supervillains who are organised by the US government to work together as a black ops team in exchange for redemption.

The movie, which is part of DC's new interconnected film universe, is scheduled to release on August 5, 2016 on both sides of the Atlantic.
