On the surface, Shazam/Captain Marvel appears very similar to DC Comics' premier hero Superman. Avid readers understand their many differences, but it would be easy for film execs to balk at the idea of doing a movie focused on what they perceive as a Superman clone. One way around this is to make Mary Marvel the central character of a "Shazam" film, with brother Billy serving a supporting role. Mary has been around almost as long as the good Captain, appearing in multiple Golden Age features and following her brother into the modern era. Her purity and sweetness lend themselves to a refreshing take on the increasingly dark world of super heroes, and Mary could even bring those qualities into the "Justice League" feature film. While Mary followed Billy in the comics, perhaps Warner Bros. could reverse course and make a progressive move with Billy becoming the spin-off character from Mary.
