"Suicide Squad" Cast

Aside from Stallone, old and new stars are set to grace the movie.

According to Deadline, the new DC film will feature a new group of villains, although the franchise needed to say goodbye to some of its pioneer actors.

Initially, Will Smith was expected to return as Deadshot. However, due to "scheduling concerns," he departed from the franchise.

Idris Elba was chosen to be Smith's replacement, but Warner Bros. and Gunn decided to offer him the new character of Robert DuBois a.k.a Bloodsport.

Meanwhile, the cast list also includes Margot Robbie (Harley Quinn), Viola Davis (Amanda Waller), John Cena (Christopher Smith/Peacemaker), Joel Kinnaman (Col. Rick Flag), Jai Courtney (George Harkness/Captain Boomerang), Peter Capaldi (Clifford DeVoe/The Thinker), Alice Braga (Sol Soria), and Pete Davidson (Richard Hertz) among others.

Variety added that Daniela Melchor will play a gender-swapped version of Batman villain Ratcatcher, while David Dastmalchian will be Polka-Dot Man.

Before the official release of the film, Empire magazine recently asked the director about the characters who will survive in the franchise.

"No character was protected by DC. They gave me carte blanche to do what I wanted. That was one of the things we agreed to before I came to work for them," he said. "I wasn't looking for shock value but I wanted the audience to know anything could happen."
