The big-screen adaptation of Dr. Seuss' classic children's book The Lorax brought in big bucks this weekend at the box office.

Featuring the voices of Zac Efron, Taylor Swift and Danny DeVito in the title role, the animated Lorax netted a massive $70.7 million in receipts in its first weekend in theaters.

Largely aided by a 3D release, the film update of the 1971 Seuss classic easily became 2012's highest-debuting flick.

Earning $17.4 million on Friday alone, The Lorax had the best opening day ever for a Dr. Seuss film, exceeding the day one take of 2000's How the Grinch Stole Christmas ($15.6 million). If early estimates hold, the film is projected to have the best opening ever for a non-sequel animated film.

The teen party thriller Project X debuted in second place this weekend, earning a $20.8 million take, which far exceeds the $12 million budget for the flick, shot over five weeks in L.A. and presented in home video format.

Rounding out this weekend's top five movies were Roselyn Sanchez's Act of Valor ($13.7 million), the Ryan Reynolds-Denzel Washington thriller Safe House ($7.2 million) and Tyler Perry's Good Deeds ($7 million).
