Zac Efron’s new film “17 Again” pushed the Disney flick Hannah Montana: The Movie from the top spot at the box office over the weekend taking an estimated $23.7 million.

“17 Again” is a new twist on the age-swap movie where a cynical middle-aged man is transformed to be, well, 17 again (these movie titles are inspired, huh?) starring heart throb, Zac Effron from the High School Music series.
