Check out the just-released trailer for Alastair Lee's latest film, BlocHeads, due out this November as part of the latest Brit Rock Film Tour extravaganza.

It's the story of UK bouldering - the practice of climbing, well, boulders unroped, which has gone from being a means of training for 'real' climbs to a sport in its own right. You can expect all the usual sumptuous cinematic footage and quirkiness plus - and we're quoting here - 'a story of adventure, rocky passions and mutant fingers. It’s the story of a search for bouldering gold'.

Top boulderers featured include Dan Varian, Ned Feehally, Jerry Moffat, Michaela Tracy, Alex Waterhouse and many more in action at some of the UK's most stunning bouldering locations from the south-west through to Northern Ireland.
