Dark Knight eyes box office record July 18, 2008 Early records expected for ‘The Dark Knight’. Box office analysts are forecasting record ticket sales this weekend in the States when the latest Batman movie, The Dark Knight, opens in 4,366 theatres — the largest number of theatres ever to show any film. The record number of theatres is expected to offset the limited number of screenings imposed by the film’s 2 1/2-hour length. Online ticket sellers have said that they are already doing record business and that some showings have already sold out. Carl DiOrio, who covers the box office for the Hollywood Reporter, wrote today that the “smart money has Dark Knight debuting somewhere south of Spider-Man 3 — which unspooled to a record $151.1 million in May 2007 — and north of Iron Man, which opened in May this year with $102.1 million.” The Dark Knight opens this side of the Atlantic July 25th – but we’ll see you all Tuesday for our advanced screening!
