Actor Mark Strong is in talks to take the role of the villainous Dr. Sivana in the upcoming Shazam! film, according to TheWrap. This would be Strong's second DC villain role, as the actor played Sinestro in 2011's Green Lantern.
Sivana, a mad scientist, is one of Shazam's oldest enemies. The character first appeared in Whiz Comics #2 back in 1940. It is still unclear whether Dwayne Johnson's Black Adam will also appear in the film as a villain, or be held for his own solo movie, which reportedly recruited a screenwriter this week.
Additionally, Variety reports that actress Grace Fulton has been cast as one of Billy Batson's friends. Though Zachary Levi will play the adult Shazam, Batson himself, the hero's adolescent alter ego, has not been cast. Fulton appeared in Annabelle: Creation, which was directed by Shazam! director David F. Sanberg.
Shazam! is scheduled for an April 5, 2019 theatrical release.
