It should be noted that there has been no official studio announcement on this matter. That said, ComicBook.com is reporting that Tyler James Williams of The Walking Dead and Everybody Hates Chris was doing an interview where the subject of him possibly playing a superhero in the future came up. "There aren't a lot of young, black superheroes," Williams responded. Then two memebers of the audience brought up Static Shock (though it should be noted that the actual name of the character is just Static. Static Shock was the name of the series) and Spider-Man, an obvious reference to the Miles Morales version.
"I don't know... What you're taking about," Williams teased the audience, before continuing, "But yeah no, it's great to see Static Shock is happening with Jaden."
ComicBook.com asserts that the "Jaden" he is referring to, obviously, is Jaden Smith, the son of former Fresh Prince of Bel-Air star and current DCCU Deadshot, Will Smith. So could Jaden Smith have already been cast as Static in the Static Shock movie? Jaden Smith was already linked to this character last year, in the form of a webseries, so it could be possible that Williams doesn't know what he's talking about, or is just engaging in some wishful thinking for his friend. Or, it could be, that Jaden will be joining his dad in the DC Cinematic Universe. We await an official announcement from Warner Bros on the matter.
