Like its subject, this 1970 film about auto racing is wildly energetic, mixing color with black and white, moving from a fictional story about three drivers to documentary footage to brief illustrated commentaries. Director Risto Jarva pokes fun at our psychological dependence on machines: women’s hands touch gas pumps as well as men, couples make out to the sound of roaring engines, and an anatomical diagram of a man reveals an engine at his center. This being Finland, some of the races take place over beautiful snow-covered country roads, but ultimately Jarva sees the auto as a dehumanizing machine that threatens to subsume our identities. Tragically, Jarva himself died young in a 1977 car crash.
