The Transformers are still on top of the U.S. box office as Harry Potter prepares to swoop in and take over at number one next week (17Jul11).
Transformers: Dark of the Moon beat out new releases Horrible Bosses and Zookeeper to stay atop the box office chart for a second successive week, after becoming the biggest release of the year (11) last week (03Jul11).
The sequel raked in $47 million (£29.3 million) over the weekend - almost twice that of second-placed Horrible Bosses ($28.1 million/£17.6 million), according to studio estimates.
Kevin James' comedy Zookeeper came in third with $21 million (£13.1 million).
