“I quite like how obscure this thing is. It’s not the biggest, it’s not the best, it’s not the tallest, it’s not the most famous; nobody knows about this thing. It’s quite unique within this landscape: I like things that stand out.” The first words off Leo Houlding about this documentary film on climbing the Mirror Wall, a 1200m slab of vertical rock in Greenland. Leo has done many, countless climbs all over the world, but this is the first one he attempted as a dad. And that changes things. Certainly, when a softball-sized granite rock hits Leo as he is resting in his hammock suspended off the cliff, destroys his sleeping bag and realizes the rock could have been bigger.
