Slightly different weekend numbers (i.e., different than Steve Mason‘s) came in an hour ago. Mason had The Forbidden Kingdom at $19 million for the weekend vs. $18 million earned by Forgetting Sarah Marshall. But a rival studio estimate has the Kingdom at $21,175,000 vs. $16,858,000 — a gap of almost $4.5 million. Expelled, the right-wing propaganda doc, came in ninth with $3,400,000 and $2200 a print…dead. And 88 Minutes, the Jon Avnet-Al Pacino thriller, will earn a lousy $6,992,000 by Sunday night.
