When HBO was the home of all the best movies, the biggest blockbusters, they needed to look and sound like the movies they showed. This was not tv, this was HBO! So the IDs and all the branding elements contained mini-movies, as though HBO actually WAS the movies. Several genres were chosen: action-adventure, comedy, family, espionage, and more.
We had to create mini movie underscores to make each element feel and smell like a blockbuster. So we recorded a 60 piece orchestra and sweetened in post, and we did live foley sfx to make each element completely believable. The results are truly cinematic in scope.
