Zac Efron may be cute, but he’s no Hannah Montana.

This weekend the Disney veteran got a chance to prove his worth in his first starring role. And though he managed to hit #1, Efron pulled in approximately $8.6 million less than Miley Cyrus did last week. The premiere of 17 Again also opened to $18.3 million less than High School Musical 3 did last October. (Then again, those two family-friendly films were a bit more accessible with their G-ratings.)

Russell Crowe, in the meantime, had far much more to groan about. The Oscar winner found his new movie, State of Play, sandwiched in between the two tween idols. The thriller, costarring Ben Affleck and Rachel McAdams, earned nearly $10 million less than the age-reversal comedy for a second place finish.
