The greatest cult movie you've never seen: an uncompleted science-fiction fantasy about ecological destruction, shot in and around a UFO convention at Giant Rock and Los Angeles in 1969 and 1970.

In September, the Horse Hospital will host an exhibition that documents and recreates an extraordinary lost pop culture artefact, Saturation 70.

This visionary film project— a Wizard of Oz for the 60s counter-culture — was helmed by writer and director Tony Foutz and starred Julian Jones Leitch (the then five year-old son of Brian Jones), Gram Parsons, Michelle Phillips (of the Mamas and the Papas), Stash Klossowski de Rola (the bon vivant son of painter Balthus) and couturier to the stars, Nudie Cohn (of ‘Nudie suit’ fame).

Principal photography on Saturation 70 was all-but-complete when the funding fell through. The footage subsequently disappeared.

The exhibition at the Horse Hospital will feature all that remains of the project: pages from the script, a series of never-before-seen production stills and behind-the-scenes photos from the Saturation 70 shoot, alongside a screening of the only-existing footage from the film, a five minute showreel cut to the Flying Burrito Brother’s version of the Rolling Stones’ Wild Horses.

PRIVATE VIEW: FRIDAY 5TH SEPTEMBER 7PM

EXHIBITION: SAT 6TH SEPTEMBER – SAT 27TH SEPTEMBER, MON – SAT, 12 – 6PM

AN AUDIENCE WITH DONOVAN: SATURDAY 6TH SEPTEMBER, 8PM
