For the Leonardo DiCaprio-Martin Scorsese pairing earned an estimated $22.2 million, out-grossing any new releases and putting its total box office at over $75 million. Of the new releases, Kevin Smith’s buddy comedy Cop Out, starring Bruce Willis and Tracy Morgan, was the highest grosser with a $18.5 million opener and a second-place spot in the rankings. Overture Films’ R-rated horror film The Crazies debuted at $16.5 million for third place.

Avatar continues to astound. James Cameron’s extravaganza fell only 14% its eleventh weekend in theaters to gross an additional $14 million, putting its domestic gross at an unbelievable $706 million. The minimal drop will give Twentieth Century Fox added ammunition as it tries to hold onto 3-D screens opposite Disney’s Alice in Wonderland next weekend. Fifth place belonged to Fox’s Percy Jackson and the Olympians. The PG-rated film is one of the only family films in the marketplace and its $9.8 million gross, representing a scant 36% fall, illustrates the movie’s staying power.

The rest of the top ten was dominated by holdovers. Warner Bros.’ Valentine’s Day took the 6th slot with an additional $9.5 million. The ensemble romantic comedy has now earned $100 million. Seventh place belonged to Dear John, the Sony film financed by Relativity Media, that grossed an estimated $5 million its fourth weekend in theaters. The 30% drop brings the Amanda Seyfried- Channing Tatum romance to a total cume of $72.6 million. R-rated The Wolfman held onto the 8th slot, grossing $4 million for a total gross of $57 million. The Tooth Fairy took spot nine, earning $3.4 million. The Dwayne Johnson-starrer has now grossed an estimated $54 million. And slot ten went to the Oscar-nominated Crazy Heart, whichearned $2.5 million for the tenth spot at the box office. The Jeff Bridges vehicle has now earned an impressive $25 million, a figure that’s likely to grow if Bridges wins the Oscar for Best Actor at the Academy Awards next weekend.
