Nathan Fillion has been added to the cast of The Suicide Squad

A long-time collaborator of James Gunn’s looks to be joining his upcoming reboot of The Suicide Squad.

In an exclusive for Deadline, it has been revealed that Nathan Fillion is joining the cast of James Gunn’s The Suicide Squad.

As of now, his role is undisclosed, but Fillion has previously worked with Gunn on Slither and Super, as well as a cameo role as a hulking prisoner in Guardians of the Galaxy and as Simon Williams/Wonder Man in a deleted scene of Guardians of the Galaxy Vol. 2.

Fillion is arguably most famous for his roles as Captain Reynolds in the short-lived series Firefly and as the titular character of Castle, and he currently stars in the ABC drama The Rookie. However, he is no stranger to the DC side of the comic book world either as he has been a staple of DC animated films for years.

He previously voiced Steve Trevor in the 2009 animated Wonder Woman film and has voiced Hal Jordan in various other animated films – the most recent being The Death of Superman and Reign of the Supermen. Furthermore, he also voiced Vigilante in several episodes of Justice League Unlimited.

With his role not being announced right now, speculation as to who he is playing is bound to be incoming.

From his résumé, there’s potential that he could be portraying another character from The Flash’s rogues gallery, such as a slightly more charismatic Captain Cold. Or, he could be playing a character from Batman’s rogues like Hush.

It’s possible that he could even be reprising his role of Hal Jordan in live-action, however, given the project, this is highly unlikely.

No matter who he is playing though, Fillion always brings a great amount of charm and fun to the screen.

The Suicide Squad is set to begin production on September 23 and is slated for an August 6, 2021 release date. Are you excited that Fillion is joining the cast? Let us know in the comments below!
