End Day is a 2005 docu-drama produced by the BBC. It aired on the National Geographic Channel, on the TV series National Geographic Channel Presents, and BBC Three. It depicts a set of five doomsday scenarios. The documentary follows the fictional scientist Dr. Howell, played by Glenn Conroy, as he travels from his London hotel room to his laboratory in New York City, and shows how each scenario affects his journey as well as those around him, with various experts providing commentary on that specific disaster as it unfolds. After each 'End Day' runs its course, the day repeats, this time with the next scenario panning out. The following descriptions of the program were released by the BBC:

Scenarios

Below are the various catastrophes depicted in the order they occur in the film:

Mega-Tsunami

Killer Meteorite

Global Pandemic

Supervolcano

Strange Matter

Alternate versions

All original official sources cite five different scenarios including a giant volcanic explosion, but the volcanic explosion segment has never been aired in the United States. It has been edited out by the National Geographic Channel. Possibly for time problems or the inaccurate depiction of the Western United States and Yellowstone park. All references to it on the National Geographic website have been removed. Only the other four scenarios have been aired. However, the BBC website had the super volcano segment until it was removed sometime after 28 May. 2006. UKTV History aired the version including the supervolcano segment on 23 January 2007. However, in the original BBC airing each of the scenarios showed the attempts of a family or person to escape the depicted disaster as well as following Dr. Howell, these segments were mostly cut from the UKTV History version aired in 2007. The volcano sequence can however be found on the popular video website YouTube. A French-dubbed version of End Day was also aired in France (on the channel W9 ) and in Belgium (on RTBF ), under the title Fin du monde : les quatre scénarios (End day: the four scenarios). The "super volcano" scenario was not included.

In-film references

At one point when Dr. Howell drives off in a taxi at the beginning of the second segment, a front of a cinema is visible behind with "Groundhog Day now showing". In Groundhog Day, the protagonist is stuck in a single day of his life, repeating it time after time with minor variations – similar to the life of Dr. Howell. Transitions between the disasters are shown such that it turns out that the prior disaster was actually a movie on a TV that has been left running overnight and the credits would roll as Dr. Howell's alarm clock goes off.
