I frankly do not know what to make of this. The article is puzzling:
It claims a SF State graduate by the name of Joseph Vogt directed both a PSA pro seatbelt-use (titled "Impact") and "Smoking Fetus".
The article goes on to describe the ad:
Sounds like the clip often credited to Fincher, right?
I am afraid this post will have an equally unsatisfying ending as "Zodiac". I did quite some research on "Joseph Vogt" and couldn't come up with anything useful. So in how far Vogt and Fincher have to do with one another (e.g. one stealing the other's credits, or being the pseudonym of the other) or whether the legendary ACS ad really is Fincher's work ... I cannot say.
What's more troubling is that Joseph Vogt went on to work on Rick Springfield's "Bop Til You Drop" -- yet another prominent credit on Fincher's filmography.
I'm all out of ideas on this. If anyone has or can come up with any info on this, I am sure we will all appreciate it!
