You got to love London. Why? Just listen to this. The Tin Tabernacle is a stunning iron church in Kilburn – and the interior of the building has been designed to look like the inside of a ship. Throw in three of the best adventure documentaries ever made and you have yourself London magic. Something to make this event even more special is that it's organised in aid of the children's charity Kids Company. Films sneak peek: - The Swimming Granny: The first film is about an 85-year-old granny who swims every day in the sea, tottering into the water with great waves all around her. She found it helped cure her postnatal depression when she was a young woman and has been swimming in the sea ever since. By Heiðrik á Heygum. 8 minutes. - North Of The Sun: Two Norwegians find an islolated beach in the Arctic circle where they surf for 9 months in the dark. They build a beautiful cabin out of driftwood and collect rubbish on the beach. The ultimate hut fantasy film. By Inge Wegge and Jørn Ranum. 46 minutes. This one's won over 21 international film awards. - And Then We Swam: Two friends decide to row across the Indian Ocean. Far from being extreme athletes, neither had actually ever rowed before in their lives. But four months earlier, determined to prove their doubters wrong, they got their secondhand boat to the start line on the west coast of Australia, and set off. By Ben Finney. 37 minutes. Winner of Best Film at the Banff Mountain Film Festival 2014.
