Sylvester Stallone joins cast of The Suicide Squad

Actor will feature alongside Margot Robbie, Idris Elba and more in the DC Comics sequel

Director James Gunn has announced that Sylvester Stallone is joining the cast of The Suicide Squad.

The film is a combined sequel to and soft reboot of the 2016 DC Comics adaptation Suicide Squad, and sees a roster of supervillains team up to form an Avengers-esque supergroup.

Stallone joins an ensemble cast which already includes Idris Elba, John Cena, Peter Capaldi, and Pete Davidson.

Margot Robbie and Viola Davis will also be reprising their roles, of Harley Quinn and Amanda Waller respectively, from the original 2016 film.

Gunn, who is best known for directing Marvel’s Guardians of the Galaxy, posted a picture of himself and Stallone on Instagram.

Beside the image, he wrote: “Always love working with my friend @officialslystallone & our work today on #TheSuicideSquad was no exception. 

“Despite Sly being an iconic movie star, most people still don’t have any idea what an amazing actor this guy is.”

The Rocky star then also confirmed the news on his own Instagram page, sharing a photo of a news outlet reporting his casting, along with the message: “Working with this incredible Director on this astounding project has made this an amazing year. I am a very lucky man to be surrounded by such talent.”
