“Hexaplex”

Hello Thomas.
I have a revision for one of the articles [previously] appearing on in70mm.com - “A Century of Widescreens at the World's Fairs”
Section 18 refers to Expo 1992 - Seville / Spain. I was involved in the
production of the “Hexaplex” film and can offer some additional
information and corrections:
The Hexaplex system was devised by Mike Browning, who had considerable
experience in special format cinema systems. The film format was 35mm for
both camera and projector. The camera rig consisted of 6 interlocked Arri
cameras arranged to cover a full 360 degree panorama. The cameras rotated at
slow speed around a vertical axis, which had the effect of moving the joins
between the panels. The viewing theatre consisted of six flat screens set up
to form a closed hexagon with their edges almost touching. Front projection
was employed. Each projector was mounted directly opposite its respective
screen and with it lens just above the top edge of the opposite screen. The
projectors and screens remained fixed in position. The audience were all
seated inside the hexagon on a platform which revolved at slow speed once
the film had started. At this distance in time I cannot remember whether the
cameras and the seats rotated in the same or opposite directions, but the
effect while viewing the film was to make the joins between panels
un-noticeable. Only one film was ever made in the process.

Dear Thomas,
Along with my colleague Phillip Grace, correcting the mistakes in the "HEXIPLEX"
(Seville 1992) section of this article, I draw your attention the the
absence of any mention of THE RAINBOW SERPENT THEATRE, the Australian
government pavilion presentation at World Expo 88 in Brisbane
Shot in VistaVision with a
camera of my manufacture, this complex presentation featured a rock cave
with a live actor and two 70MM interlocked projectors. The front projector
beamed images by Pepper's Ghost into the cave while the rear projector
displayed a changing landscape beyond the stage, reflected in black glass.
The 6 track sound was magnetic from the front projector. The Actor mimed the
narration and synchronised his actions with the film images, unseen by him.
At the end of the show he disappears behind his exploding campfire and a
giant snake takes his place, whirls around the stage and flies from the cave
into the hills as they transform from desert landscape to lush green with
emerging lakes...
A very complex, wonderful 70MM show
