The phantom ride was a genre of film popular in the very early days of cinema. A camera was fixed to a moving vehicle to simulate a journey for an immobile cinema audience. They sat pinned to their seats, white-knuckled for fear they might derail on the next precipitous bend. The train tracks or the road anticipated the trajectory of the ‘phantom’ vehicle. Here though, the way has vanished. The highly precise and repeatable movements of the huge robotic arm on the similarly track-bound ‘motion control camera’ used to make this film facilitate a rollercoaster ride on invisible rails. The film’s soundtrack is the only remaining evidence of the camera’s week-long presence in the Duveens – the audible contractions and expansions, the ascents, descents and contortions, of a very real machine. -- Simon Starling
