'Avatar' Leads Box Office for 4th Straight Week

Sunday brought James Cameron's newest flick to the end of it's fourth week at number 1 in the box office, making it the second-biggest movie of all time. The number 1 spot held by Cameron's previous film, 'Titanic'

James Cameron's 3-D sci-fi epic earned $48.5 million across the United States and Canada during the three-day period beginning Friday, distributor 20th Century Fox said.

Its total rose to $429.0 million, making it the seventh-biggest movie of all time in North America, before accounting for inflation. The last movie to enjoy four consecutive weekends at No. 1 was the Batman movie, The Dark Knight, in 2008.

"Avatar" is the tale of a disabled ex-Marine sent from Earth to infiltrate a race of 10-foot (3-meter) blue aliens and persuade them to let his employer mine their homeland for natural resources. It was reportedly the most expensive film ever made, with a budget of at least $300 million.
