The animated movie version of Dr. Seuss story "The Lorax" climbed to the top of weekend box office charts with a stronger-than-expected nearly 71 million dollars (USD) in U.S. and Canadian ticket sales, studio estimates released on Sunday (March 04) showed.

The film tells the story of a young boy who must discover the story of Lorax in order to win the affection of a girl he likes. Zac Efron and Taylor Swift lend their voices to the project.

Second-place belonged to the film "Project X," a new comedy about a group of high school students who throw a party that gets out of hand. The film took in a respectable 21 million at domestic theaters from Friday through Sunday.

Rounding out the top three was the "Act of Valor," a military drama in its second weekend in theaters, with 13.7 million.
