Some of these pictures and descriptions may give away plot details that you might not want to know before watching the film.
"If you're going to race with the Devil, you've got to be as Fast As Hell!"
"Peter Fonda and Warren Oates are burning their bridges and a lot of rubber... on the deadliest stretch of road in the country!"
In a motor home interior scene full of tension and terror (as long as you don't know anything about snakes) a woman goes to make coffee and finds a couple of rattlesnakes (western diamond-backs I think) in the cupboard. They were put in there by the demonic cult members who have been following them across Texas. The snakes leap out of the cupboard as if they were spring loaded (as do all snakes in movies) then terrify the two screaming women and two men who wrestle with them forever and try to kill the snakes with a ski pole. Fonda grabs one by the neck and whips it to death then they toss them out the trailer door. I read that the actors are actually handling live rattlesnakes that were "milked" of their venom making them less dangerous. That's dedication to your craft.
