I suspected after 9/11 that air fares would drop sharply with no one wanting to travel, and I was right. A week or two later I bought a very reasonably-priced round-trip fare to Paris. By the same token I’ve been thinking that perhaps a certain percentage of moviegoers might not want to see The Dark Knight Rises this weekend after last night’s tragedy, and that I could slip in at the last moment and snag an IMAX seat. No such luck. Deadline‘s Nikki Finke says there’s been no slowdown at all today and that Chris Nolan‘s film might take in as much as $180 to $200 million by Sunday night.
