''Damnation Alley'' is a 1977 science-fiction thriller set in a post-apocalyptic world.
WorldWarIII happens. The crew at a remote US Air Force missile base survive the war, but following an accident which kills several of them and destroys most of their supplies, the remainder decide to make their way across the country to the only part of the USA that is still inhabitable. Unfortunately, the only way to get there is a narrow strip of not-quite lethal wasteland, dubbed by the leader of the expedition as "Damnation Alley". As the name suggests, it's no picnic. They set out in two "[=LandMaster=]" armored vehicles, encountering various dangers and other survivors as they travel east.
The [=LandMaster=] prop is arguably the best thing in this movie, and went on to have almost as long [[PropRecycling a career in cinema]] as the human star, Jan-Michael Vincent.
Very [[InNameOnly vaguely inspired]] by the [[Literature/DamnationAlley novel of the same name]] by Creator/RogerZelazny.
Best known for being the blockbuster 20th Century-Fox was expecting in the summer of '77, if not [[Franchise/StarWars the one they got]].
!!The movie contains examples of:
* ActingForTwo: Only one [=LandMaster=] was actually built for the movie. One of the "twins" gets destroyed early on.
* AwesomePersonnelCarrier: The [=LandMaster=]. Armed to the teeth with [[StuffBlowingUp rockets, mortars]] and [[MoreDakka machine-guns]], amphibious, large enough to hold several people comfortably (complete with bathroom and shower), an internal navigation system and radio, with a triple-wheel arrangement on each axle that allows it to go over obstacles with minimum fuzz.

* AttackOfTheKillerWhatever: The cockroaches of Salt Lake City.
* BlackDudeDiesFirst: Strictly speaking averted, in that he's not the first to die, but he doesn't come close to surviving the trip either. The fact he is played by Paul Winfield assures his fate.
* CoolCar: If the [=LandMaster=] can be called a "car".
* CosyCatastrophe: The people of Albany have apparently been doing quite well despite the catastrophe.
* HeyItsThatGuy: A teenage JackieEarleHaley is one of the survivors.
* RoadTripPlot: From the Nevada desert to Albany, New York (the only parent safe zone left in post-nuke America).
* SafeZoneHopeSpot: Blithely subverted with Albany. Although it's discussed early on that it could be this trope played straight (an automated radio broadcast, etc), the town survived.
* ScaryScorpions: Giant mutated ones make a brief appearance.
* TechnologyMarchesOn: Minor example: the "computer guidance system" on the Landmaster was actually an advanced (for the film's production year) [[http://en.wikipedia.org/wiki/Texas_Instruments Texas Instruments]] desk calculator.
* TheSwarm: The cockroaches again.
* ThereWasADoor: The [=LandMaster=] is used to blast into and out of a parking garage.
* WackyWaysideTribe: A small group of survivors (hinted to be cannibals) threaten the companions at one point. [[CurbStompBattle They are disposed of easily]], with a few [[BoomHeadshot head shots]], a well-thrown rock, and [[StuffBlowingUp the LandMaster's rocket launcher]].
