Britdoc, now in its third year, has opened applications for The Big Pitch, it's Dragon's Den-style international pitching forum.
Investors and comissioning editors from the US, Europe and Asia will participate. Last year's panel included experts from HBO, IFC, ARTE, Sundance Institute, ITVS, NHK Japan, Netflix, Discovery Films and SBS Australia.
More than $2m (£1m) in funding has been raised in each of the Big Pitch's past two editions.
'The results speak for themselves,' said Jess Search, chief executive of The Channel 4 British Documentary Film Foundation. 'Over two thirds of the projects pitched at BRITDOC 07 are now receiving funding.'
Twelve film-makers will pitch before the funders and an audience.
One recent success story from Big Pitch is Jerry Rothwell's Heavy Load, which secured funding from IFC and YLE Finland after Britdoc.
Application information is available at the Britdoc site and the deadline is June 13.
Britdoc runs July 23-25.
