Reading the various comments posted, I'm saddened to see that Nic Roeg is receiving the credit for this amazing film. Granted, Roeg did provide his always stunning camera work to the film, but it was Donald Cammell who wrote, directed the actors, and edited (along with Frank Mazzola) PERFORMANCE.
Roeg acted as DP on the film, blocking the camera movements as Cammell worked with the actors. In fact, according to Cammell, they worked so well together that people would comment "...the two director approach is the wave of the future." Cammell also revealed that his admiration for Roeg's work was somewhat tempered by the fact that Roeg was often solely credited for PERFORMANCE, something that just isn't true.
Don't get me wrong, I think Nic Roeg is a wonderful director and a brilliant DP. DON'T LOOK NOW, THE MAN WHO FELL TO EARTH, and BAD TIMING are some of my favorite films, but PERFORMANCE is Cammell's vision more than Roeg's.
In fact, given the ironic and tragic life that Cammell led, perhaps it's only fitting that he would be overlooked for his work on PERFORMANCE, which displays his obsessions for Borges, gender/identity, and sexuality.
