Berlin based artist Julian Rosefeldt will be the next artist featured at the BFI Gallery at London's Southbank Centre (currently hosting John Akomfrah's Mnemosyne). Rosefeldt initially trained as an architect but now specialises in large multi-channel films which play with narrative and sonic conventions in cinema. The work to be shown, American Night is a "political Western" about recent US foreign policy and was partly shot on a former Sergio Leone film set in southern Spain. The title refers to a technique in which footage shot in the daytime is filtered to imitate the look of that shot during night, a widely used effect in Cowboy and Western genre films. London BFI Southbank, 10 September–7 November, free.
