"Shazam!" screenwriter, John August, has posted on his official website, that Jake Gyllenhaal has not been approached to play Captain Marvel, in the upcoming movie which August has been hired to write:

But the thing is, he's not considering. I can pretty much assure you he's never heard of the project. And we've never discussed him. We've never seriously discussed anyone.

After several months of meetings, casting has come up exactly zero times. There's no casting list. If there were a list, Gyllenhaal's name would probably be on it, but trust me: there is no list. There's no start date, no release date, no movie whatsoever. There's just a script to be written. Which I should probably get back to.

No word on when production will begin on the film!
