1st week of Transformers: $165 million
1st week of Spider-Man 3: $182 million
1st week of Shrek the Third: $150 million
1st week of Pirates of the Caribbean: At World's End: $173
I feel like I'm starting to sound like a broke record, because I've said this over and over, but Transformers will pass up Pirates. Pirates had a HUUUUGE first 4 full days (that means not counting the Thursday evenings showing it received) and after that it died out FAST. It took Pirates 44 days after the first 4 to double it's domestic total.
I know only 15 million seperates Pirates from Shrek, but for some reason I don't think Transformers will pass up Shrek, I think it'll beat out Pirates by about 5 million or so.

soooo close...
