If you’ve never visited the hectic locale of an urban arcade—or left the house—you may not be familiar with DDR or Dance Dance Revolution, the Konami-produced interactive music video game series that spawned a subculture of sun-shy dance mat devotees across the globe.

It’s popularity is owed partly to its simple set-up, by which players step on corresponding arrows as they light up in time to music, as well as the growing hysteria induced as its difficulty and intensity increase exponentially the longer it’s played.

UpDownLeftRight, a new film by London-based director Oscar Hudson, follows Dance Dance Revolution whizz Hiroyuki Imamura, who, after a secret video of him dancing went viral on YouTube, was dubbed the God of DDR.
