Called A 1,000 Years of History, the promo features series presenter Michael Wood guiding viewers through a photo-real "timeline". It was designed and directed by Richard Acton of BBC Broadcast and shot on green-screen before Red head of visual effects Chris Mortimer motion tracked, animated and lit each scene in Inferno. Each timeline was individually composed and animated to suit the live action. Oliver Smith supplied additional calligraphy while Tony Naqvi completed the "clock" graphics. The promo airs from this week.
