Did it matter those were real people?

Just saw GWoS here in Vancouver at the VIFF... I didn't know seeing it that any of the auditions were real people.. and after seeing the movie and reading up on it, and now knowing the fact, I've come to the realization that it didn't make the slightest bit of difference.

GWoS wasn't about the auditions, it was about the sales guys. It was their story. The auditions were just minor players. I saw description on an MTV blog that described this movie as a "Borat-styled docudrama". The problem with that description is it brings its own set of expectations that the audience is completely aware at all times that the "real life victims" are being conned (or punk'd, or whatever) for the audience's amusement, and that setup is the purpose of the film. That is not what happened in this film.

If the GWoS filmmakers had fictionalized all the auditions entirely, it would have made no difference to the audience. The movie as it's presented is about the two sales people, conning while they themselves are being conned. The fact that the auditions are real (a fact only discovered by reading outside the movie, never detailed within the movie) is actually completely irrelevant to the storytelling.

Am I wrong? Is it important, or just trivia that they were real?

(I will acknowledge one benefit in having real people is that on a low buget film, taping real people versus finding actors for all those audtions was a plus.. but that's a benefit to "making the film", which is different than what I'm talking about here.)
