THE DA VINCI CODE will do very well because it has a cult following of "true believers" (like a Michael Moore film), but word of mouth will ultimately hold its totals down. The only thing that kept it from being the most critically reviled film this week was the presence of SEE NO EVIL, a ludicrous slasher film with wrestling star Kane as the monster.
And that's what they said about SW TPM too and it made 417 mil in the US alone.
