It wasn’t long ago that AICN broke the story that Mackenzie Grey was LEX LUTHOR in MAN OF STEEL. While they were correct in stating that he is indeed in the film, the rumor exploded all over the internet and showed that even the Heavyweights in the industry can be wrong.
According to CBR, their ‘inside source’ suggests that Zach Snyder is wanting to cast Mark Strong as LEX LUTHOR, in the already eagerly anticipated MAN OF STEEL 2:
The source says it’s been said that filming for the Man of Steel sequel will be begin next year, and Mark Strong is wanted for Lex Luthor by Zack Snyder. Expect pre-production to start coming together by October-December.
David Goyer is hard at work on a first draft of the screenplay for Man of Steel 2. The source says Chris Nolan is sort of overseeing the script/story, but may not have as much input as before as he is focusing on his new film project, Interstellar.
While I suspect that this is mere speculation, I would certainly love to see Strong in the role. He’s a fantastic character actor who has the ability to make unlikable characters, likeable.
