Frank Grillo made his DCU debut as Rick Flag Sr. in Creature Commandos, and the response from fans was largely positive. However, in Peacemaker Season 2, we saw a completely different, far more villainous side of the new A.R.G.U.S. Director.
While he rightly wanted revenge on Christopher Smith for his son's death in The Suicide Squad, Flag Sr. took things too far when he got coked up while his men died and made a deal with Lex Luthor in a bid to find Salvation.
In the Season 2 finale, he left Peacemaker on the alien planet to die. It was a twisted move, especially as Chris has found redemption and established Checkmate as a force for good. As for Flag Sr., he's become one of the DCU's most reviled characters, news which shocked Grillo.
"Right now, I am? I didn't know that!" Grillo says in the video below after learning how hated the character is. "Peacemaker killed my son! Let me help you here. He murdered my son, my child." When the interviewer pointed out that Peacemaker had turned over a new leaf, the actor replied, "Whose problem is it, mine or yours? You're crazy."
After a brief role in Superman, Grillo will return as Flag Sr. in next summer's Man of Tomorrow. The extent of his role in the sequel isn't clear, though he'll likely be the one who frees Luthor to take the fight to Brainiac. Whether Salvation comes into play remains to be seen.
In Man of Tomorrow, Superman will be forced to team up with Lex Luthor to battle Brainiac, a threat not just to Metropolis but to the entire world.
Written and directed by James Gunn, the movie stars include David Corenswet as Clark Kent/Superman, Nicholas Hoult as Lex Luthor, Lars Eidinger as Brainiac, Rachel Brosnahan as Lois Lane, Skyler Gisondo as Jimmy Olsen, Sara Sampaio as Eve Teschmacher, Frank Grillo as Rick Flag, Sr., Aaron Pierre as John Stewart, Nathan Fillion as Guy Gardner, Edi Gathegi as Mister Terrific, and Milly Alcock as Supergirl.
Andre Royo, Matthew Lillard, Sinqua Walls, and Adria Arjona will also star. However, as we mentioned above, we still don't know whether the latter is playing Maxima or Wonder Woman. There's also speculation that Eva De Dominici is playing one of the characters, and there's always a chance the Diana Prince rumblings don't pan out. We'll have to wait and see.
Man of Tomorrow arrives in theaters on July 9, 2027.
