Flex is a 2000 video installation by the British video artist Chris Cunningham. It consists of a 15 minute film loop that endlessly depicts a naked man and woman floating in darkness, who by turns embrace and furiously beat one another, culminating in an act of anal sex during which they disappear in a blast of light. The film is set to an electronic soundtrack by Aphex Twin.
It was first displayed to the public in 2000 as part of the Apocalypse: Beauty and Horror in Contemporary Art exhibition and subsequently at the Anthony d'Offay Gallery and other art galleries.
A 3.5 minute excerpt of the 17-minute film was released on the DVD The Work of Director Chris Cunningham.
The full 17 minute video was shown in the Barbican’s exhibition Seduced: Art and Sex from Antiquity to Now curated by Martin Kemp, Marina Wallace and Joanne Bernstein. alongside other pieces by Bacon, Klimt,Rembrandt, Rodin and Picasso.
The man and woman are depicted by combining the performances of a number of performers and body doubles, including actors Jon and Jo Hadfield, and dancers Rob Tannion and Desiree Kongerod.
Post-production work was done at Glassworks and the Moving Picture Company
