Mark Strong is no stranger to the DC Universe, having previously played Sinestro in the Ryan Reynolds Green Lantern movie. He's been given a chance to redeem himself after that disaster of a movie as he's now in talks for the role of Doctor Sivana in Shazam!.
Doctor Sivana is Shazam's longtime arch-nemesis, debuting alongside the hero in 1940's Whiz Comics No. 2. He's the typical mad scientist, but he's squandered his gifts, leaving him twisted and bitter.
Shazam!, directed by David F. Sandberg, stars Zachary Levi as the titular character and is set to release April 2019.
