The obvious answer would seem to be Roeg. The splintered style, the swirling camerawork, the intense colours and reliance on scripts best described as hallucinatory (Eureka, Bad Timing, Walkabout) that mark his later work are abundantly present in Performance. But this impression is partially false. We think of Performance as Roeg's first fully-fledged vision because we're so much more aware of the Roeg canon. He, like Cammell, would have collisions with the studio system, but Roeg's movies would (until recently) receive wide distribution. Cammell's com- mercial misfires - namely the misogynist nightmare Demon Seed and the serial killer thriller White of the Eye - have barely seen the light of day, and are, unfortunately, seldom revived, so very few know that they are as visually extravagant and as dislocated as anything Roeg has offered.
The extraordinary White of the Eye in particular traffics in flashbacks, fast-cutting and a use of filters that simultaneously recalls Roeg while seeming the essence of Cammell. Likewise the film's voyeristic detachment from, but plain fascination with, the killer's sexuality and his convoluted relationship with his wife recalls Performance at its finest, as well as echoing Bad Timing.
So the puzzle of authorship remains, if puzzle it is. Perhaps Performance was - is - no more, and no less, than a meeting of minds. And technique. And obsessions. Whatever, it remains both men's crowning achievement, unless Cammell's The Wild Side springs a last minute surprise equal to White of the Eye's explosive finale.
