Expendables 2 continues chart hold

Expendables 2 has continued its grip on the North American box office chart, holding onto the number one spot for a second consecutive week.

The movie, which sees action stars including Sylvester Stallone, Arnold Schwarzenegger and Bruce Willis reunite, took $13.5m (£8.5m).
The Bourne Legacy remained at two in its third week of release, with $9.3m.
Stop-motion comedy ParaNorman, about a boy who helps save his town from a zombie invasion, was at three.

Typical of late summer openings, other new releases performed weakly in the chart.
Thriller Premium Rush, starring Joseph Gordon Levitt as a bike messenger chased through New York by a policeman who wants an envelope he's carrying, opened at seven with $6.3m.
And low-budget road-chase comedy Hit & Run, starring real-life couple Dax Shepard and Kristen Bell, entered at 10 with $4.7m.
With less competition from big Hollywood films, it allowed anti-President Barack Obama documentary, 2016: Obama's America, to land at number eight.
After opening in limited release in July, it expanded nationwide ahead of the Republican National Convention to formally nominate Mitt Romney as Mr Obama's challenger in the presidential race.
The film is a conservative critique envisioning what the US would look like four years from now if Mr Obama was re-elected.
