The weekly sales reports are in again courtesy of Rentrak for the week ending January 16, 2011. Last week’s biggest selling movie comes as no surpise as Oscar front-runner The Social Network takes the #1 spot. Though, in a somewhat surprising appearance (at least I think so), the animated movie Alpha and Omega debuts in the #2 spot. This drops last week’s front-runners Machete and Dinner for Schmucks to the #3 and #4 spots respectively. Despicable Me rounds out the top five as Eclipse still holds strong in its 7th week at number six.
