Is Gnostic teaching prevalent in the film industry?

Hollywood film director Richard Stanley said this:

I guess one could see the whole of the mass media as it stands today as some sort of extension of the gnostic faith…maybe cinema itself is acting as some kind of hand maiden to the apocalypse.i

When asked if they were aware of the Gnostic theme of The Matrix, the Wachowskis, who directed the film, replied, “Do you consider that to be a good thing? I would.”ii

If these popular directors give any indication, Hollywood is embracing and teaching Gnosticism as truth. What, then, is Gnosticism, and where can we find it permeating the mass media?
