In 2009, Prologue created a promo advertising HBO’s original series HBO Docs. The promo begins with a with a shot looking ahead from the front of a moving train, which is cut back to twice more in the sequence. Stock footage of previous documentaries and historic events begins to fly by, along with audio derived from that footage. Between the documentary clips, graphics showing video stills of various projects are seen floating around an empty space next to short descriptions of what those projects entail. The video stills come together to form the title HBO Docs, along with its premier and air time.
