Benedict Cumberbatch's Wikileaks drama The Fifth Estate has topped Forbes' list of 2013 film flops.

The movie bombed after it opened in October (13), bringing in just $6 million (£4 million) in global box office takings, and Forbes writers have now named it the worst performing film of the year (13) as it earned back just 21 per cent of its $28 million (£18.7 million) budget.

WikiLeaks founder Julian Assange, who is played by Cumberbatch in the movie, publicly opposed the project and correctly predicted the film would flop at the box office.

Other releases included in Forbes' 'turkey' list include Sylvester Stallone's Bullet To The Head and Harrison Ford's Paranoia, which ranked second and third respectively.

Jason Statham and Jennifer Lopez's crime thriller Parker was ranked the fourth worst performing film while Mark Wahlberg's political drama Broken City completed the top five.
