After writing about a recent survey of French artist Philippe Parreno at the Serpentine Gallery last year, I found myself wondering about his collaboration with the Scottish artist Douglas Gordon. In 2006 the two artists made the acclaimed film Zidane: A 21st Century Portrait, and while Parreno’s skills as a film-maker were pretty evident from that first UK solo exhibition, Gordon’s talents must surely lie elsewhere - that is, outside the frame. Neither technically ambitious nor visually seductive, his films are not even meant to be seen in their entirety, certainly not his 1993 24-hour Psycho, which is simply a frame-by-frame re-presentation of the Hitchcock classic.

West Coast pop art always was a poor relation to the world-beating New York original. Beside the Big Apple titans – Andy Warhol, Roy Lichtenstein and Claes Oldenburg – LA painters such as Ed Ruscha, Robert Irwin and John Altoon remained essentially local figures. Or that’s certainly the way it has looked from this side of the pond.
