Demand has also experimented with film in works such as "Tunnel" (1999), a tracking shot from a driver’s perspective through an empty tunnel lined by concrete pillars; the tunnel is modelled on the Paris underpass where Princess Diana died. "Recorder" (2002) is a 35 mm-film loop in which a paper model of an eight-track reel-to-reel recording device appears to play the Beach Boys album Smile (1966), a recording that was until recently lost; the sound of a piano playing a variation on ‘Bicycle Rider’, an instrumental from the Smile sessions, can be heard on the soundtrack. "Rolltreppe (Escalator)" (2000) is an animation of 24 still images shown in a continual loop. Showing an escalator without people, taken from surveillance footage, Demand here is referencing an escalator near Charing Cross Bridge in London where a gang was caught on surveillance camera shortly after they had robbed two men and thrown them into the Thames, killing one of them. "Trick" (2004) refers back to the beginnings of cinema and is based on one of the first films of the Lumière brothers, "Assiettes tournantes (Turning Plates)" of 1896. The one-minute film re-creates a sequence in which a performer executes a stunt by spinning a set of bowls and plates on a tabletop. "Camera" (2007) presents a surveillance camera as it pans a public space, complete with ambient sound. In "Rain" (2008), Demand painstakingly re-created the effect of raindrops falling onto a hard surface, using cellophane candy wrappers and a sound track of eggs frying.
