Snakes on Film

Killers Mickey and Mallory stumble across a den of rattlesnakes and are bitten. The photography is fast and furious in this scene, but it’s possible to make out that most of the snakes in the medium shots are Western Diamond-backed Rattlesnakes (Crotalus atrox), which is an appropriate choice. In the grainy, blurry, black-and-white closeups of snakes striking, I think they substituted in a harmless Bullsnake or Gopher Snake (Pituophis catenifer); they have similar coloration.

Then they’re off to a drug store to get some rattlesnake antivenin — or, as they call it, “snake-bite juice.” It’s sold out on the shelves, so Mickey goes for the pharmacist, who manages to blurt out, “Don’t carry it. Hospital,” before he gets shot. Here’s the thing: antivenin isn’t stocked by pharmacies, and it would never have been available on the shelves. It’s always administered in hospitals: bite victims would have to be monitored for an allergic reaction to the antivenin, which might be deadlier, in some cases, than the snakebite itself.
