/New Line?s ?Shazam? may not have a superhero with the name recognition of Batman, Wonder Woman, or Aquaman; but it is doing quite well at the box office with an estimated $53.4 million opening weekend from 4,217 screens. When advance screenings held two weeks ago by Fandango are factored in, the domestic launch for David F. Sandberg?s superhero film comes in at $56.7 million, with $6 million coming from 405 domestic IMAX screns. That roughly matches the opening weekend for ?Ant-Man,? another film with a superhero that had little pre-existing name recognition.
