This is one of the most unintentionally funny snake scenes in a movie. While they're being hunted by a bunch of guys in a forest, Jean-Claude Van Damme stops and tells his female companion to close her eyes. She thinks he's going to kiss her and puckers up, but instead he grabs the neck of a rattlesnake that is just about to bite her on the neck. He smacks the snake on top of its head then punches it in the face to knock it out. Then he bites off the rattle to silence it because next he puts it up in a tree and makes a trap with some vines so it will bite whoever trips the wire. One of their pursuers trips the wire and the snake comes swinging down fangs first right into his face. He rolls around on the ground screaming with the snake still attached. His companions curse, pull the snake off his face, and blow its head off.
Don't call the Humane Association just yet, it was only a horrible fake snake, the kind that's accompanied with the kind of exaggerated explosive hissing and rattling sound effects that we unfortunately have to suffer through whenever we see a rattlesnake in a movie.
