The old guys in The Expendables 2 are likely to clobber the fresh-faced contenders in three low-budget features opening this weekend. Box office pundits say that only the action flick Premium Rush has any chance of effectively challenging last week's winner, but none is expected to earn more than $8-12 million. The other two are the romcom Hit & Run , which opened on Wednesday with a measly $625,000, and the horror flick The Apparition, which was not screened for critics -- a Common practice when it comes to the horror genre -- and is debuting in only about 800 theaters. Rush and Run each received mostly positive reviews. Expanding into more than 1,000 theaters this weekend, Dinesh D'Souza's anti-Obama documentary 2016 Obama's America could surprise. Online ticket seller Fandango said that it has sold more advance tickets for it than any other movie this weekend. In just a handful of theaters, it has already hauled in more than $2.4 million. Meanwhile, The Expendables is expected to come in at around $12-15 million.
