The whole thing is an ad for Rolling Thunder's own services, of course, and all the CG was done in house. It does all look very shiny, and we're suckers for glowing blue cityscapes with weird-shaped buildings and flying vehicles. At the same time, the trailer tries to mock the pomposity and grandeur of American trailers, but the satire actually rebounds onto the whole "Dubai is so futuristic" argument, by showing just how fake those pretty images really are.
And as various commenters have already pointed out, you can see some spaceships from Star Trek, Battlestar Galactica and other shows flying around Dubai. Do they know something we don't?
