Audiences didn’t open their wallets to see the infamous rivalry between the Sharks and the Jets play out on the big screen. West Side Story, Steven Spielberg’s remake of the classic musical, fell flat in its box office debut, collecting a paltry $10.5 million from 2,820 theaters. That’s cause for concern because Disney and 20th Century Studios spent $100 million to revive the Shakespearean love story for modern times and stand to lose millions, unless West Side Story endures at the box office through the holidays and Oscar season.
