Since the "Anchorman 2" scorched-earth Ron Burgundy marketing juggernaut started in March, there's been a Ben & Jerry's ice cream tie-in, an Anchorman exhibit at Washington, D.C.'s Newseum, and those 70 Dodge Durango commercials. And, "Anchorman 2: The Legend Continues" has already racked up about 50 million mentions on social media — more than 50,000 this week alone. That's more than all of the other movies opening Dec. 18 combined.
