Jason Momoa is returning to the DC universe — but his reign as Aquaman has ended. Instead, Momoa has signed on to play antihero Lobo in “Supergirl: Woman Of Tomorrow.”

The superhero movie — starring “House of the Dragon” actor Milly Alcock as the eponymous hero, also known as Kara Zor-El — is set to be the second film in James Gunn and Peter Safran’s rebooted DC Universe following the highly anticipated “Superman,” starring David Corenswet as the Man of Steel and Rachel Brosnahan as Lois Lane.

Craig Gillespie is directing the film, which also features Matthias Schoenaerts as villain Krem of the Yellow Hill and Eve Ridley as Ruthye Mary Knolle. Ana Nogueira (“The Vampire Diaries”) wrote the screenplay based on the run of DC comics by Tom King and Bilquis Evely.

Momoa confirmed the casting news on Instagram by sharing a quote from an interview with Fandango during the press...
