There be numbers here!
You might think that all interest in the Pirates of the Caribbean franchise had been drained away during the lackluster final chapter. Somewhere in those 5 hours of Part 3, you had probably said "enough already with the pirates" and vowed to never come back. You broke that vow this weekend.
On Stranger Tides, the fourth film in the trilogy, came in at #1 with $90 million dollars.
Also notable under an onslaught like that, Bridesmaids had a pretty good second week, dropping only 20% to $20 million. Doesn't seem like much in comparison, but remember that Kristin Wiig doesn't cost as much as Johnny Depp. Everything else in the top ten sank like a frigate in the thrall of a Kraken.
