Sam has documented a Thai boxing match, with two cameras showing the perspective of each fighter, presented side-by-side on the screen in identical timelines. But the element that makes Walker's debut video really powerful is that the fight is between two small boys.

Sam, who's directed some of Fallon's promos for the BBC - including two new Blast ads - and a couple of shorts, has had this double camera idea for a while.

Part of the strength of his idea is its simplicity - that made it easy to explain to those involved in the filming. And the unflinching way the cameras follow each child's progress demands a reaction.
