Ay, glad to find a fellow summer '01 box office fan. That's when I first got into box office so it holds a certain nostalgia for me. Especially tracking JP3's and The Mummy Return's run. Pretty hilarious now to know how weak those two are in the history of big box office runs, but at the time it seemed very impressive to 11 year old me.
EDIT: Woah, looks like Mummy Returns was the second biggest OW ever at the time. No wonder it seemed like a big deal. Insane to think that in 16 years its went from #2 to #113.
