James Gunn recently confirmed that Frank Grillo will appear as Rick Flag Sr. in Superman.

The veteran actor is set to make his DCU debut in the upcoming animated series Creature Commandos as Rick Flag Sr., the leader of the titular team. He will reprise the role in the second season of Peacemaker.

There have been rumors that he will also appear in Superman after he was spotted on the set while it was in production last summer. Fortunately, the DC Studios co-chairman has finally confirmed what we already suspected.

Gunn confirmed in a recent interview that Grillo will be reprising the role of Rick Flag Sr. in Superman.

While he didn't reveal the character's role in the story of the film, he teased Grillo's portrayal and how he will be explored in the different DCU projects.

"He is a really cool character that Frank has been molding. The character's also in Superman, and he's an incredibly important part in Peacemaker," the DC Studios co-chairman said.

"He is one of the primary characters in Peacemaker season 2. So we get to see this character from different angles, and he is not simple."

Gunn added, "This isn't just a good guy, not at all. We see all different sides of his character. He is morally a complex human being. Grillo is somebody who I've known for a little while, and I've wanted to work with him for a long time."

He also shared that Grillo was "one of the first people that I talked to when I took over the studio."

It seems that DC Studios is setting up Grillo's Rick Flag Sr. as one of the pivotal characters in the DCU given how he's already set to appear in multiple projects and how Gunn has been teasing his appearances.

Grillo has proven in his past works that he is a talented actor, especially in the action genre so it is exciting to see what his take on the character looks like. Given how DC Studios has been high for him, we can expect nothing else but a promising portrayal.
