I work for loews theaters, and we got a fax from sony pictures today, stating that we can start to pre sell Spidey tix today 4/15/2002!!
So go to any lowes theater, and they should have them in their computers.
At my theater, in Danvers MA, we can sell tix for May 3 thru 9, for times @ 10:45, 1:45, 4:45, 7:45, and 10:45.
p.s. I'd call first to make sure your theater has the ability to pre sell that early.
