User experience design is currently such a nebulous concept that a few people aren’t even sure it can be considered it’s own job title. It seems to fall under so many umbrellas (and its so new) that it doesn’t seem fair for this thread.
That said, Sittig didn’t join Facebook until after the events of The Social Network, so someone had to do the user interface design before him and that someone was likely Mark Zuckerberg. And on the third hand, just browsing a few articles on Sittig, nearly all of them refer to him as just the “designer,” a much more broad job title.
The Wright Brothers were bicycle repair men before they started working on flying machines. There must be at least one movie based on their story, surely.
Michelle Rodriguez’s character was a food truck vendor in *Machete. *It is debatable whether she or Jessica Alba is the female lead in that one though.
Ahh, I have seen the movie in a long time, I just remember someone bouncing around on the runway and someone else saying (paraphrased) “We have to allow 5 miles between planes for turbulence and he stands on the runway”
There is also a reality TV series called Parking Wars on A&E that features parking enforcement officers. (I fully expect that every profession and job will be featured in a reality series sooner or later.)
