The two animated candidates now occupy the middle of the Top Ten list.
Surf's Up came in at #4 on Friday, with a $5.1 million take.
Our old friend Shrek landed at #5, with a haul of $4,300,000. S3 has now collected a $270.4 million domestic gross.
The top two slots are filled by 1) George Clooney and Associates ($11.6 million) and (#2) Knocked Up ($6.2 million).
Update: To nobody's surprise, Ocean's 13 cops the top spot, snaring $37 million in its opening weekend (with the Koch calculator (c) predicting a final take of between $100 million and $140 million -- give or take -- for O13's final domestic tally.)
Johnny Depp and his merry band of cutthroats bring home $21.3 million for a total of $253.6 million (and Pirates is now in #2.)
The baby comedy KU declines less (34.8%) than anything else in the Top Ten, collecting $20 million and a #3 berth for a $66.2 million total after two weekends.
As for the animated entries, Surf's Up collected $18 million in its opening frame, which is no doubt a bit of a disappointment for Sony Pictures Animation, but still good enough for a fourth place finish in a competitive field. SPA's sophomore effort will probably finish south of Open Season. Our guess: it winds up in the $58-$80 million range.
Lastly, Shrek the Third collected $15.8 million for a $281.9 million total and 43.8% decline in its fourth week of release.
Update 2: Variety notes that this summer weekend was a little weaker than year-ago numbers. Ocean's 13 opened slightly smaller than its two predecessors, and Surf's Up probably got bashed by the Big Mean Ogre.
