In most years, January tends to be the most boring month of the year for the box office. This is where Hollywood typically sends the movies in which it has the least faith. This is the dumping ground, the place where movies go to die so the studios can concentrate on their Oscar campaigns. However, thanks to ‘American Sniper,’ this January has bucked every trend. It may technically be a 2014 release, but Clint Eastwood’s war film has made the first chunk of 2015 interesting, shattering expectations and threatening to become the highest grossing film of last year in only a few weeks.
