PHILADELPHIA (CBS) - Boy, did Dr. Seuss have the box-office juice.

The animated feature, Dr. Seuss' The Lorax, with a voice cast led by Zac Efron and Danny DeVito, ran away to a first-place finish on its debut weekend, earning an estimated and surprising $71-million.

Second place belonged to another new attraction, Project X, the found-footage teen party romp.  It took in $21-million in its first weekend.

Last weekend's leader -- the Navy SEALS thriller, Act of Valor -- placed third with $14-million.

No other title -- new or old -- came anywhere near the $10-million mark.

Overall, it was another in a string of strong 2012 weekends, with industry-wide totals well ahead of last year's pace.
