The recent release of Guardians of the Galaxy Vol. 3 marks an end to Gunn’s trilogy of Marvel films and his time in the MCU as he moves into a role as head of DC Studios. The director’s first order of business will be to launch the new DCU with a passion project of his own, Superman: Legacy.
After it was confirmed that Henry Cavill would not be the DCU’s Superman, the door is wide open for a new actor to wear the cape and a new cast to fill the rest of the famous ensemble, which may include some MCU stars.
Guardians of the Galaxy Actors Will Appear in Superman: Legacy
James Gunn has teased that some MCU actors will be appearing in his new DC film, Superman: Legacy, in a Q&A on Twitter.
Gunn did not confirm how many actors from his MCU trilogy would be appearing or whether the parts would be simple cameos or larger roles.
So Which Marvel Star(s) Will Appear in Superman?
James Gunn is in a rare position as someone who has worked across both major superhero movie franchises, having directed three Guardians of the Galaxy films for Marvel and also Peacemaker and The Suicide Squad for DC.
He's also well-known as a director who likes to work with the same actors. Just recently, Peacemaker star Chukwudi Iwuji appeared as the High Evolutionary in Guardians of the Galaxy 3, which is just one of many instances where Gunn has cast one of his frequent collaborators across his superhero franchises.
Actors like Michael Rooker, Nathan Fillion and Sean Gunn have all starred in both MCU and DCU projects under Gunn, some even appearing in multiple different roles, so it would be easy to see them follow Gunn onto Superman as well. There are also some Marvel stars, such as Chris Pratt and Karen Gillan, who are yet to make their DC debut and could be potential picks for a Superman: Legacy role.
Regardless, while Guardians of the Galaxy may be done for now, the cast members still have a bright future in the superhero world under James Gunn.
DC Studios’ Superman: Legacy arrives in theaters on July 11, 2025.
