Shazam! premiered a new trailer at Comic-Con today.
The trailer opens on Billy Batson, a young child, going into foster care. Another child jokingly warns him that he’s being placed with a tough family. While riding the train home one day, Batson hears a voice tell him he’s been chosen. The train opens into an icy cave, where a man with bright white hair asks him to say his name. When Batson laughs at the name Shazam, he is transformed into an adult (Zachary Levi). The suit imbues him with extraordinary powers, including super strength. The trailer also gives us a glimpse of Dr. Thaddeus Sivana (Mark Strong), the main antagonist in the film.
