Humourous

As you're probably all aware, films often feature scenes including human excrement, vomit and semen (well, the films I watch do anyway). These excretions are often produced to a high standard, which got me thinking: There must, somewhere in the world, be a company that produces these on-screen bodily fluids and solids. This in turn got me thinking that, as there's probably a lot of money involved in creating this stuff, there must be fairly rigorous procedures used in the creation of this mock-bile. But what might these procedures be? And what is used as source material for the cini-goo?

I imagine a meeting at this office to go something like this:

Boss: Jones, we have a 3pm deadline for this one. It's a film called 'There's Something About Mary', a lot of money involved. They've asked for state of the art semen, as it plays a major part in the movie. We're working to a strict time limit here, so we'll need you to order some flour, tapioca and egg whites from catering. Oh, and we need a fresh batch of source material to work from. Order some magazines and get David on the case with that one. I want you to then head up the team of bileuticians and create as close a match as possible. There could be a Christmas bonus in this if you do a good job, Jones.

Do you think that's what happens? And is it a similar process for the other bodily products I mentioned? I bet you're all thinking about how they do it now. We must be told!
