DOCFEST, Sheffield's annual documentary film festival, is a national treasure. But don't despair if you missed out - London's got plenty of options.

Take the new website, www.joiningthedots.tv  - an online, pay-per-view library of documentary films. Brainchild of Portobello-based movie distributor Mercury Media, the site already houses more than 80 hand-picked documentaries for a little as £1.50 a viewing.

"This way you don't have to wait around for the doc to get on TV," says Mercury Media's Kas Basma. "And if it does make it to the box, it doesn't disappear straight after."

With more documentaries being made than TV slots and cinemas will take on, the surplus now has a home. But for those addicted to big screen, the group also collaborate with Picture House cinemas to reveal the pic of their roster every six weeks.
