“In 1984, Indiana Jones and the Temple of Doom, the second film in the franchise, spent 12 weeks in the top 10. Five years later, Indiana Jones and the Last Crusade spent 10 weeks in the top 10. Today, eight weeks in the top 10 — which generally requires that a movie is playing in at least 1,000 locations — is a significant achievement. By contrast, some of this summer’s less successful movies had the theatrical half-life of a June lightning bug; one or two weekends and they fell off the radar.”
