Will Smith’s ‘Legend’ sets record

? For the last man on Earth, Will Smith sure has a lot of friends.

The Warner Bros. tale “I Am Legend,” starring Smith as a plague survivor who may be the last living human, debuted with $76.5 million, the biggest December opening ever and a personal best for one of Hollywood’s top box-office champs, according to studio estimates Sunday.

“It’s no wonder Will Smith feels so lonely. Everyone else on Earth is in the movie theater,” said Paul Dergarabedian, president of box-office tracker Media By Numbers.

Based on the Richard Matheson novel filmed twice before as Vincent Price’s “The Last Man on Earth” and Charlton Heston’s “The Omega Man,” “I Am Legend” casts Smith as a scientist trying to find a cure and fighting off the vestiges of humanity, people transformed by the plague into vampire-like creatures.

The 20th Century Fox family flick “Alvin and the Chipmunks,” starring Jason Lee in a big-screen take on the cartoon critters, opened a strong No. 2 with $45 million. The two films combined to give Hollywood a year-end surge after a drowsy fall season.

The previous No. 1 movie, New Line Cinema’s fantasy “The Golden Compass,” nose-dived in its second weekend, coming in third with $9 million, down a dismal 65 percent from its less-than-expected $25.8 million debut a week earlier.
