Shazam!

“Just say the word.”

Billy Batson (Asher Angel) is a teenage foster kid who gets chosen by an ancient wizard to be his champion. One magic word, "Shazam," turns him into a grown man with superpowers (Zachary Levi). Sandberg has him test it all out with his foster brother Freddy Freeman (Jack Dylan Grazer), while Dr. Sivana (Mark Strong) comes after the same power, and Billy is still a kid inside.
