Variety has an article about TW opening day & the weekend box office totals:
Summit Entertainment’s "Twilight" could see an opening day take of $30 million from 3,419 playdates after grossing north of $7 million in Thursday midnight shows.
"Twilight'" is expected to open in the $50 million to $60 million range, although it has a shot of ending in the 60s. It depends upon how much traffic slows down from Friday to Saturday.
