You certainly know both of the actors involved in this. The two actors at this point were both C list. They had already descended from their highest levels (B+ with A list name recognition) and were now staring at their own mediocrity and failed careers. On this movie though they were stars and filming outside the US and in the middle of nowhere. Well, with nothing to do at night, the two were doing non-stop drugs day and night. Well, one night they woke up the animal wrangler for the movie and paid him a significant amount of money to bring them a sheep. I don't need to go into details, but it is fair to say they both took a turn.
