Reuters reports that the 2007 movie Alvin and the Chipmunks was released on DVD last Tuesday, debuting at the No. 1 spot and selling 2.6 million copies. This really comes as no surprise, considering the movie raked in $44.3 million on its opening weekend in U.S. theaters and went on to become a box office hit garnering $215 million.

“I Am Legend,” No. 1 on both charts the previous week, slipped to No. 3 on both.

The DVD release also catapulted the film’s CD soundtrack up 11 places to No. 5 on the Billboard 200 Wednesday.
