'Grey' Wins, 'Red Tails' Hangs On, Groupon Fizzles

"The Grey" won the weekend with $20 million, good news for this original outside-the-system actioner, good news for Liam Neeson, who apparently owns the winter.

"Red Tails" dipped 44 percent -- it's hanging in there, no word yet from George Lucas on whether the numbers warrant expanding to a trilogy. He has two prospective Tuskegee Airman movies (leading up to the war, after the war) in development.

Katherine Heigl's "One for the Money," made $11 million, about a million of which (estimated by BO MOJO) came from Groupon buyers. About 20 million received a Groupon blast last week.

Opening this week: "Chronicle," "Woman in Black," "Big Miracle" and "Declaration of War."
