Los Angeles - The North American box-office rankings were topped over the weekend by the newly opened 17 Again, as the teen comedy starring heartthrob Zac Efron collected three-day ticket sales of 24.1 million dollars, according to preliminary studio estimates.

The movie stars Friends actor Matthew Perry and Efron, who became a teen idol in the High School Musical films, as the old and young versions of a middle-aged man who wakes up to find himself a teenager again and attending high school with his own children. (dpa)
