Rebecca Rubin Film and Media Reporter “Creed III” delivered a powerful box office knockout with its $58.6 million domestic debut, clobbering expectations and franchise records in the process. And there’s more good news for struggling theater owners starved for compelling content. It looks like the good fortune will continue in March with “Scream VI” (March 10), “Shazam: Fury of the Gods” (March 17), “John Wick: Chapter 4” (March 24) and “Dungeons and Dragons: Honor Among Thieves” (March 31). There’s at least one major release every weekend through the rest of the month, offering the kind of stability that’s been desperately missing during the great box office reset.
