I stumbled on this Shell-produced documentary almost by accident: I've been preparing a book that collects the writings of the Turku-based film critic Tapani Maskula (a Finnish legend), and reading some of his reviews from the sixties I noticed that he said nice things about a short subject that was shown before a longer movie (I believe it was The Hallelujah Trail). The short film was called Shellarama, and it was supposed to be shown in 70 mm (in Cinerama, to be exact), but there haven't been any 70 mm projectors in Turku, so it must've been shown here in 35 mm.
As the title suggests, Shellarama is, to quote the film's IMDb entry, "a celebration of Shell Petroleum, tracing its manufacture from discovery in oil fields to its eventual use as fuel for modern living across the globe". The film contains lots of breath-taking aerial shots with long camera drives over deserts and jungles, and it's fascinating to watch. Here's BFI on the film, I believe they have released the film - and some other 70 mm short films - on DVD or Blu-Ray.
Shellarama is available via YouTube in its entirety, albeit not with a very good quality, but it's still worth your while. As I watched it, I got to thinking the film reminded me of a much later film, Godfrey Reggio's Koyaanisqatsi from the early eighties. Both films are without dialogue or voice-over narration, and both films are structured rather similarly, as both start from nature and continue on to big cities and their car jams. Both films contain similar shots of industrial enviroments and cities. Both films use people almost only as backdrops. Of course the ideology between the two films couldn't be more different: Shellarama praises Shell and oil that is used to promote modern life, while Koyaanisqatsi criticizes the modern life and the turmoil it brings to Earth. The music in the films couldn't also be more different from each other, as Koyaanisqatsi uses Philip Glass's minimalist soundtrack and Shellarama has some Latin percussion.
It's still entirely possible Godfrey Reggio was influenced by Shellarama. If he wasn't, I'm surprised!
But take a look and see for yourselves. Looks like Blogger crops the embedded clip, here's the direct link to YouTube. (More Overlooked Films at Todd Mason's blog.)
