With an hour to kill due to a dental appt., I thought I'd have a go at the intro skyscraper. At first I assumed it would be the roof of the Adams Mark, but no. It's a black building with a "step" design (first photo). In the second photo, note the tilings as well as the two buildings on Phil's right: the
D&F clock tower and
Independence Plaza. Behind Phil's back is Mile High stadium in the distance (you can see it if you advance the video a few frames). Using GE and Emporis and
Denver Skyscrapers, I've chosen
Plaza Tower as the most likely candidate. Most of it fits: the exterior appearance, the sightline (photo below with the Plaza upper-right and the clock tower bottom-left), and the motley tiling (kmz attached). The building next to it is a bit troubling, but maybe it's shorter than the Plaza.
