Acclaimed Hollywood filmmaker James Cameron's re-release of sci-fi epic movie Avatar has been reported a flop at the US box office at the weekend. The horror film The Last Exorcism topped the box office chart, debuting with $21.3 million in earnings, followed closely by Takers, the crime drama starring Chris Brown, Hayden Christensen and Matt Dillon opening with $21 million, reports contactmusic.com.

Meanwhile, Cameron's 3-D special edition of Avatar, which included an extra nine minutes of footage, failed to draw cinemagoers in droves as it did last year. The film pulled up merely $4 million.

Sylvester Stallone's action hit The Expendables slipped to third place with $9.5 million, raising its three-week total to $82 million.

Rounding out the top five were Julia Roberts' feel-good film Eat Pray Love and Samuel L. Jackson's action comedy The Other Guys, taking in $7 million and $6.6 million respectively.
