I’m back for another week of the top selling and most rented movies on DVD and Blu-ray. These results come from data gathered by Rentrak for the week ending February 20, 2011. This week sees only one newcomer breaking the top ten. That comes as no surprise really, though, as last week saw only one real major release. That newcomer: the Tony Scott thriller Unstoppable which lands in the top spot in sales. Meanwhile, disappointingly, Beverly Hills Chihuahua 2 remains in second place for DVD/Blu-ray sales. Sad. I know.
