Superman: Legacy Adds Three More To Cast Including Nathan Fillion As A Green Lantern

We're officially two years out from the release of "Superman: Legacy," barring any setbacks, which is currently set to come out on July 11, 2025. Director James Gunn is already making excellent headway for the first film in the new DC cinematic universe, with David Corenswet playing the Man of Steel while Rachel Brosnahan plays Lois Lane. The cast has filled out a bit more, opening up exciting possibilities for the next "Superman" movie, as revealed by Vanity Fair. 

Arguably, one of the best pieces of superhero casting in recent memory came in the form of Nathan Fillion landing the role of a Green Lantern, specifically Guy Gardner. This lines up with previous reporting that Gunn would bring on someone from "Guardians of the Galaxy Vol. 3" to the "Superman: Legacy" cast. Fillion has long been a staple of Gunn's films, most recently playing Master Karja in his last Marvel film. But that's just the beginning of how "Legacy" will blow the doors open of the new DC universe.

It appears Superman will have a world populated by other heroes to interact with in James Gunn's film. Vanity Fair goes on to report how Isabela Merced, best known for roles in "Sicario: Day of the Soldado" and "Dora and the Lost City of Gold" will portray Hawkgirl. The character had a significant role in the "Justice League" and "Justice League Unlimited" animated series, but it's great to see her getting a big-screen outing, especially after Hawkman (Aldis Hodge) got screentime in 2022's "Black Adam." 

Rounding out the new cast list is Edi Gathegi, who's appeared in the "Twilight" films as well as "X-Men: First Class." He'll play Mister Terrific, one of the world's most brilliant inventors who utilizes T-Sphere weapons. Similar to a "Guardians of the Galaxy Vol. 3" cast member entering the "Superman: Legacy" fray, Gunn has hinted at wanting to use Mister Terrific before. On November 15, 2022, the director posted an image of the character on Twitter, which many fans took to mean he was going to bring him into the universe some way, and now we know how he's going to do it. 

Is this just the beginning of a veritable age of superheroes "Superman: Legacy" could introduce? Are spin-offs on the table? Regardless, this is shaping up to be a "Superman" movie unlike any other, and Gunn is rounding up some serious talent to bring it to life.
