BBC End Day Documentary. Cool!

Homer: We're all gonna die!!! (He's shouting on the plane)

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

Mega-Tsunami

In this scenario, a volcanic eruption on the island of La Palma triggers a massive landslide wherein a sizeable portion of the island collapses into the sea, causing a massive mega-tsunami to race across the Atlantic ocean and strike the east coast of the United States, inundating New York City in particular.


Killer Asteroid

This scenario begins with a mysterious 'missile attack' in a remote area somewhere in the Middle East. The 'missiles' are soon revealed to be small asteroid fragments, the advance guard of a much larger asteroid on a collision course with Earth, threatening central Europe. The asteroid is located and an attempt is made to destroy it using nuclear ICBMs. The attempt fails, resulting in the asteroid being broken into hundreds of smaller pieces which then impact and obliterate Berlin.


Global Pandemic

In this scenario, a virus similar to SARS or Asian Bird Flu is unleashed, wreaking havoc as it spreads at a phenomenal rate throughout Europe, the UK, and North America, prompting many countries to enact martial law and close their borders in a frantic attempt to contain the spread of the disease.


Supervolcano

This scenario is based on the supervolcano beneath Yellowstone National Park erupting, causing vast damage to the area 100 km around the volcano, as well as releasing ash into the atmosphere which is predicted to severely cool the earth. This segment has only aired in the UK. This scenario was explored in depth in another BBC docudrama, Supervolcano.


Strange Matter

This scenario is the only one wherein Dr. Howell reaches his laboratory unhindered, with people protesting, and shouting,"STOP THE EXPERIMENT!" outside. Upon arrival, he and his colleagues initiate a highly controversial experiment using the world's largest particle accelerator. The experiment quickly goes out of control, resulting in the creation of a new type of matter called a strangelet, which begins to consume and destroy all matter around it, starting with New York City. The phenomenon wreaks havoc on Earth's weather systems and atmosphere, insinuating that the entire planet will eventually be destroyed.
