I was so flummoxed by this I had to learn more, so I took to Google, where I found this blog post by Dan Cardone, who was a grip on this film. Some highlights:
This was the first set I had been on that featured three directors, and hopefully the last. One director was there to primarily film the sex scenes, which he did effectively and economically. The other two directors handled what is called in porn-lingo āB-Rollā, i.e. everything non sexual. Which on this film was substantial. The plot for To The Last Man involves two ranches populated entirely by horny men who have random sex and feud over water, as they are in the middle of a crippling drought. Which is why we filmed in Arizona during thunderstorm seasonā¦
Itās amazing no one got killed, or seriously injured. There was horse riding, there were fight scenes of rocky escarpments, there were drownings. When the real guns and live ammunition came out for a scene I thought, āThatās it, Iām going back to the truckā.
Fortunately, one of the models was also a fully qualified nurse, so that saved money, time and also lives. Plus, he was sexy, so it was win/win.
