Sam Peckinpah's hallucinatory bloodbath was considered career suicide when released in 1974; today, this scuzzy, squirrelly road movie looks less like self-parody than self-autopsy. As such, it has aged better than some of Peckinpah's more "reputable" movies. Like John Cassavetes' THE KILLING OF A CHINESE BOOKIE and Brian DePalma's BLOW OUT, it's a thinly veiled allegory about the muck a filmmaker will wade through to get his movies made. Peckinpah's stand-in is Warren Oates, an actor who always brought a rotgut reek of authenticity to his roles; here, he's a washed-up pianist who stands to score a bundle if he completes one simple task--fetching the severed head of the yutz who impregnated a Mexican warlord's daughter. When Oates isn't defending his not-unwilling girlfriend (Isela Vega) from rapists Kris Kristofferson and Donnie Fritts (!), he's carrying on a boozy, uh, tête-à-tête with the brown-bagged head on an endless drive down Mexico way. But Oates isn't the villain--that distinction is reserved for the effete suits (the slimy duo of Gig Young and Robert Webber) on his tail. Oates is just a guy trying to maintain enough of his integrity to see a dirty job through: He's one of those screw-you Peckinpah heroes who completes his assignment just so he can wage war on his bosses. The movie has such a gritty, oozing, flyblown feel you could swear it was shot on No-Pest Strips instead of celluloid, and as Oates bears down on oblivion it slows to a druggy crawl: Each cut is like a dying man's blink. No matter-in its sick, ornery way, this is one of the director's most personal movies, and worthy of far better than its laughingstock status.
