What does “Superman” switch portend?

My read on Warner Bros.’s decision to release Superman Returns two days earlier — on Wednesday, 6.28 instead of Friday, 6.30 — is that the marketing cats are figuring Bryan Singer’s humungously costly film will be pretty much over and done by the time Pirates of the Caribbean: Dead Man’s Chest comes along on July 7th, so why not go for the moolah by stretching out the 4th of July weekend as much as possible? I haven’t called my pallies with the tracking reports, but the general expectation is that Superman Returns will pull in…I don’t know what to write here. Those angry Ain’t It Cool guys have been gunning for this film for months now. Will geek sentiments matter? Do geeks ever matter when it comes to huge tenpolers? Is a figure of $140 to $145 million over the six-day weekend on-the-money, optimistic, a bit short…what? What are HE readers expecting? How interested?
