The tweens once again proved that they're a force to be reckoned with when it comes to the American box-office, as Hannah Montana: The Movie coined a big $32.3 million over the weekend, to easily give it the top spot. Two other films opened lower down the charts; the edgy looking Seth Rogen comedy Observe and Report, and the kiddie action film Dragonball: Evolution, which coined $11 million, and $4.7 million respectively. The Rogen comedy was always seen as a slightly tough sell, as it's not as overtly laugh-out-loud as some of his other efforts; but fair play to the man for taking some risks we say - we're very much looking forward to it.
