Ticket sales for “Indiana Jones and the Kingdom of the Crystal Skull” jumped 23 percent to $30.8 million on Friday from an under-expectations opening day, reports Steve Mason of Fantasy Moguls. Foreseeing bigger jumps today and tomorrow, Mase is now predicting a five-day take of $148 million by the end of the day on Monday, which would make “Indy” the second best Memorial Day weekend opening ever, and the fifth-best five-day opening of all time (before figures are adjusted for inflation). “Indy” is being helped by the under-performance of “Prince Caspian,” which plummeted 66 percent on Friday from its opening day a week earlier. Mase thinks it will finish the four-day weekend with a disappointing $27.87 million, barely ahead of the long-legged “Iron Man” with a predicted $25.24 million and $257 million total in the bank. “Indy” is the weekend’s only wide release after a threatened 1,500-screen debut for Uwe Boll’s “Postal” got scaled back to 31 screens nationwide. I haven’t seen it, but you know a movie’s bad when even such notoriously un-picky venues as the Village East and the AMC Empire 25 won’t book it; its sole New York City location is the Cobble Hill Cinemas in Brooklyn. Mase reports “War” averaged $124 a screen on Friday and will be lucky to finish the weekend with $500 per venue. Despite devastating reviews, the weekend’s other new political satire posted more-than-respectable numbers on two screens on its way to DVD next month. Mase predicts “War” starring John Cusack will post a per-theater average of $16,578. Meanwhile, Paramount has replaced a blurb (“Crystal Skull earns its event status..Like any good myth, Indiana Jones Shows Up When He’s Need”) taken from the Daily Snooze critic Joe Neumaier‘s four-star (out of five) near-rave with of one (“Crystal Skull is a movie for all ages”) from the New York Times’ Mahola Dargis, who was much, much less enthusiastic about the flick.
