Danny Boyle and Nia DaCosta reminded the audience at CinemaCon’s opening night that what is dead can never die with fresh looks at the upcoming films, 28 Years Later and 28 Years Later: The Bone Temple. First, Boyle spoke to the crowd filling the Colosseum at Caesars Palace, cracking jokes about the years he’s spent in the post-apocalyptic world. “I still love blowing shit up,” the filmmaker said to the attendees, before offering a brand-new, never-before-seen trailer for the feature.
