Hannah Montana and Miley Cyrus got together and made a No. 1 movie. That's how easy it is. And it just beat out Hannah Montana/Miley Cyrus: Best of Both Worlds Concert Tour, which made $31 million its opening weekend, but it was also playing at a smaller number of screens.

Observe and Report is not going to beat Paul Blart: Mall Cop at the box office, but it did OK considering it's a dark comedy with only an $18 million budget.

Look for 17 Again with Zac Efron and Matthew Perry to dominate next week.
