[Highway] is Morrison. Morrison hitchhiking. Morrison speeding through the desert. Morrison drinking beer. Morrison pissing. Only near the end did he reveal he had killed a man and stolen his car. The picture's beauty lay in its honesty. Morrison, the star, was totally free of everything—but himself.
For those who missed the point, the film ends with a short "love is where it's at" rap by four persons bathing in a mountain stream.
