David Corewnswet's Superman is confirmed to make an appearance in the upcoming Supergirl movie. How will he fit into the Girl of Steel's solo DCU adventure?
A new trailer was recently released, giving fans another glimpse at Milly Alcock's full-time debut as Supergirl in the DCU and her galactic adventure. It also showed us a sneak peek at Corenswet's return as the Man of Steel, and fans have been looking forward to seeing how his cameo may play out in the movie's story.
How David Corenswet's Superman Will Fit Into the Supergirl Movie
In an interview with EW, director Craig Gillespie explained how Corenswet's Superman will fit into the Supergirl movie and the dynamic between the two Kryptonian characters when we see them together.
"They have such different upbringings. Superman hasn't gone through trauma. He came from a very loving family and was almost groomed to be in this role, whereas Supergirl has been through trauma and the role's kind of being pushed upon her at a later age, and she's having to adjust to that," he said.
The upcoming movie will explore the differences between Superman and Supergirl and the sibling-like relationship that they have in the world of DCU.
"Even though they're cousins, you get this almost older-sibling dynamic, and that can be adversarial at times. He's the gentle guy that wants to reach out and be patient, and she's having to find a way and find herself," he added.
Gillespie also teased that the film will feature a scene between Corenswet's Superman and a newly arrived Supergirl on Earth.
"It was actually our first day out the gate. She just landed, so she doesn't know English. So she's out of the gate speaking Kryptonian," he said.
