No he isn't. He didn't save F4 from being terrible. Fahrenheit 451 flopped too. And he's not even in the running unless you get you think We Got This Covered is a legit source.
Can't wait!
....... first of all nobodies gonna save a movie from being a flop if it has flop written all over it. Second, no ones in the running for Superman so we can speculate anyone.
Edit: Would you look at that
"To help find a way to make Superman relevant to modern audiences, studio brass has been polling lots of high-profile talent. There have been discussions with J.J. Abrams, whose company Bad Robot recently signed a massive first-look deal with the studio, and there was a meeting with
Michael B. Jordan earlier this year with the "Creed" star pitching Warners on a vision for the character. However, Jordan isn't ready to commit to taking on the project since filming doesn't seem likely to happen for several years and he has a full dance card of projects. Insiders think that a new Superman film is unlikely to hit screens before 2023, given that there's no script and no director attached."
