James Gunn's The Suicide Squad: Who's playing who

We've finally found out who's playing who in James Gunn's The Suicide Squad. Some returning characters are not a surprise, obviously, but the rest of the lineup has finally been revealed thanks to the big DC Fandome event taking place this weekend.

Gunn himself hosted the panel-slash-game show which had nearly everyone from "Task Force X," a.k.a, the Suicide Squad, in attendance.

Here's the roll call:

Viola Davis as A.R.G.U.S. director Amanda Waller

Joel Kinnaman as Colonel Rick Flag

Michael Rooker as Savant

Flula Borg as Javelin

Margot Robbie as Harley Quinn

David Dastmalchian as Polka-Dot Man

Daniela Melchior as Ratcatcher 2

Idris Elba as Bloodsport

Steve Agee as King Shark

Mayling Ng as Mongal

Peter Capaldi as The Thinker

Alice Braga as Solsoria

Pete Davidson as Blackguard

Nathan Fillion as TDK

Sean Gunn as Weasel

Jai Courtney as Captain Boomerang

John Cena as Peacemaker

Other in the cast include Storm Reid, Taika Waititi, Joaquín Cosío, Julio Ruiz, Tinashe Kajese, Jennifer Holland, and Juan Diego Botto.

Aside from the roll call's massive lineup, Gunn introduced a sneak peek at the behind-the-scenes of the film.

The director claims that "It's gonna be different from any superhero movie ever made," and producer James Safran even calls it a "gritty, 1970s war movie combined with (the) brilliance of James Gunn's characters and comedy." 

The Suicide Squad is written and directed by Gunn and will come out in 2021.
