Get a load of this when you have the time. It's a little over twenty minutes.
I saw it earlier in the eventing at a live broadcast of Rifftrax, one where they brought back a lot of old MST3K people, including Joel a couple of times.
Anyway, this safety film is a rich target being the three G's: goofy, gory, and grim. But it's kind of artful as well. The shots are well centered. The guy playing the foreman, at least, is a natural. As it turns out the film was made by Herk Harvey, the director of the cult classic Carnival of Souls. Which makes you wonder about the metaphysics of this construction site.
