After Batman v Superman, Suicide Squad, and Justice League, all of which exist in the same universe, Shazam! looks like it's going to be a breath of fresh air for the DC Extended Universe. Very happy, very silly fresh air.
If you're unfamiliar with the classic superhero and/or not been following io9's coverage, Shazam the superhero is, in fact, a young boy named Billy Batson (played by Asher Angel), who transforms into an adult superhero (Chuck's Zachary Levi) when he yells "Shazam!" As the trailer shows, Billy is totally down with his new powers — and his new age.
Shazam! shazams it's way into theatres on April 2019.
