The Twilight Saga: New Moon, the latest vampire-werewolf centered film marketed towards 14-year-old girls and (inappropriate) forty-somethings, debuted on DVD and Blu-Ray last Saturday and sold a staggering four million copies during its opening weekend, according to Collider.

Four. Million. Copies. Does anyone remember that scene in the original Invasion of the Body Snatchers, when that wave of horror washes over Kevin McCarthy’s face just as he realizes that everyone he knows has been replaced with a duplicate pod person? Me too, guys—me too.

The first Twilight film sold 3.8 million copies in its opening weekend before steamrolling on to sell nine million copies total. Despite the fact that DVD sales have been in a slump as of late, expect The Twilight Saga: New Moon to do business equal to its predecessor, if not better, between now and the inevitable release of The Twilight Sage: Eclipse on June 30th (which–gasp!–got a new theatrical poster this week).

In other news, rumors ran rampant in Hollywood that Twilight star Kristen Stewart made a facial expression. More on that story as it develops.
