High-Ballin (1978)

Featuring Peter Fonda and Jerry Reed, we're not at the bottom of the 1978 truckin' barrel yet.

Steel Cowboy (1978)

There is seemingly no end to these trucking films. Another one from 1978, this time with James Brolin and Rip Torn.

White Line Fever (1975)

Not really in the same league as Road Movie but part of the oil crisis/70s recession-era obsession with instigating the automobile's integral accident -- this time with trucks. The big year for trucker movies was 1978, with Peckinpah's Convoy and Clint Eastwood's Every Which Way But Loose exploiting the exploitation movies. But White Line Fever, with Jan-Michael Vincent and Slim Pickens, is more pissed off and therefore gets my vote.

Road Movie (1974)

Forget Moonfire, for real existential truck action Joseph Strick's Road Movie is the only real choice. Strick did some great work on The Savage Eye (1959) but spent years making films that attempted to adapt the unadaptable -- Joyce, Genet, Henry Miller. Road Movie is much better: raw, awkward and alienating.

Moonfire (1973)

The most authentic trucking movie ever made? Who would know?
The whole film is available on Youtube here.
