Hadley's appearance is a silent cameo, where the character is only seen from the neck down, due to Henry Cavill being unavailable to film the scene.[18] Dwayne Johnson's likeness is used for the mystically-generated holograph of Teth-Adam, which the wizard Shazam conjures while teaching Billy the history of the Rock of Eternity, the Seven Realms of Magic, and his previous Champion.[19] Johnson will portray the titular role in Black Adam.[6]
