Is Frank Grillo’s Rick Flag Sr. In James Gunn’s Superman Movie?

Is Frank Grillo in Superman?

Frank Grillo Rick Flag Sr Creature Commandos DC Universe

Could Frank Grillo be joining the cast of Superman? A new social media post suggests Rick Flag Sr. will appear in James Gunn’s next DC Universe project.

James Gunn made waves when he announced that Frank Grillo would be joining the DC Universe as Rick Flag Sr. in Creature Commandos. It’s a near-perfect casting choice, and brings an actor made for the world of comic book movies back into the fold when Marvel wasted him as Crossbones.

However, it seems fans may be seeing Rick Flag Sr. in live-action sooner than they expected. A new post by Frank Grillo on Instagram reveals the actor is headed to Atlanta, which is near where James Gunn will be shooting Superman in the coming weeks. While it’s far from confirmation, it may be fans’ first hints of a truly connected DC Universe.

Frank Grillo’s Future In The DC Universe

Frank Grillo is officially set to make his DC Universe debut as Rick Flag Sr. in Creature Commandos, an animated series developed by James Gunn for Max. The character is the father of Rick Flag, a character best known through Joel Kinnaman’s role in the Suicide Squad franchise.

However, it seems Rick Flag Sr. won’t be confined to Creature Commandos. The actor revealed that he’s in the DC Universe for the long haul, teasing plans with James Gunn and Peter Safran that he wasn’t able to reveal. Could this be a tease that he’ll be playing a small role in Superman?

Given James Gunn wrote both Superman and Creature Commandos, it wouldn’t be out of the question for cast members like Frank Grillo to crossover. Especially with Gunn trying to establish a new DC Universe, it could be helpful to have connections like Rick Flag Sr. for audiences to latch onto.

Superman is currently scheduled to open in theaters on July 11, 2025. Stay tuned for the latest news regarding the future of the DC Universe and make sure to subscribe to our YouTube channel for more content!
