sequels, which generally performed well, were scheduled and only four—The Dark Knight, The Chronicles of Narnia: Prince Caspian, The Mummy: Tomb of the Dragon Emperor, and Indiana Jones and the Kingdom of the Crystal Skull—were predicted to be blockbusters. Kingdom of the Crystal Skull was the only film expected to easily earn over $300million. The Dark Knight was expected to sell well based on high audience anticipation, positive pre-release reviews, and a record $3.5million in IMAX pre-sales. Predictions placed its opening-weekend take above that of Iron Mans $102.1million but below that of Spider-Man 3s (2007) record $151.1million. Analysts said its success would be influenced by the lengthy running time that limited the number of screenings per day, and counter-programming from the romantic comedy Mamma Mia!—which surveyed well with women—and the family comedy Space Chimps. There was also a perceived limit on financial success for Batman films; the 1989 installment remained the franchise's highest-grossing release. The Dark Knights premiere took place on July 14, in IMAX in New York City. A block in Broadway was closed for the event, which included a live performance of the film score by Howard and Zimmer. The Hollywood Reporter said Ledger received several ovations, and that during the after-party, Warner Bros. executives struggled to maintain a balance between celebrating the successful response and commemorating Ledger. Box office On July 18, 2008, The Dark Knight was widely released in the U.S. and Canada in a record 4,366 theaters on an estimated 9,200 screens. It earned $158.4million during the weekend, a per-theater average of $36,282, breaking Spider-Man 3s record and making it the number-one film ahead of Mamma Mia! ($27.8million) and Hancock ($14million) in its third weekend. It set further records for the highest-grossing single-day ($67.2million on the Friday), Sunday ($43.6million), midnight opening ($18.5million, from 3,000 midnight screenings), and IMAX opening ($6.3million from about 94 locations), as well as the second-highest-grossing Saturday ($47.7million) behind Spider-Man 3, and contributed to the highest-grossing weekend on record ($253.6million). The film benefited from repeat viewings by younger audiences and had broad appeal, with 52% of the audience being male and an equal number of those under 25 years old, and those of 25 or older. The Dark Knight broke more records, including for the highest-grossing opening week ($238.6million), and for three-, four-, five-, six-, seven-, eight-, nine-, and ten-day cumulative grosses, including the highest-grossing non-holiday Monday ($24.5million) and non-opening Tuesday ($20.9million,
