"Earth Day turned into Christmas for 20th Century Fox Home Entertainment last week as consumers clamored to re-visit Pandora.
To no one's surprise, Hollywood's top earning movie at the box office with a $2.7 billion global haul, shattered records around the world with the release of its DVD and Blu-ray over the weekend.
As of Sunday afternoon, the film had sold 6.7 million copies in four days in North America alone, according to retailers and sources close to the studio. Of that, 2.7 million were on Blu-ray, shattering the record that previous best-seller "The Dark Knight" had reached. That pic took 18 months to sell 2.5 million Blu-rays."
