There are a myriad of TV movies and series (e.g., 24, Six Feet Under, Lost, Terminator: The Sarah Connors Chronicles, etc.) that have a minor character or subplot that could be survivalist-related. They're often touted as survivalist media references but in actuality, many have little to do with the realities of survivalism or survival retreats. Here are a few exceptions:
The Colony – A Discovery reality series that follows groups attempting to survive under simulated conditions of a global catastrophe.
The Day After – A 1983 TV movie about events before and after a three-hundred-plus Soviet ICBM nuclear attack on the United States.
Jericho – A 2006 series following the story of Jericho, Kansas, in the wake of a massive nuclear attack on the United States.
The Fire Next Time – A 1993 miniseries about the struggle of a family to survive the catastrophic effects of global warming and the resulting chaos.
Survivor – A competitive “reality” series in which contestants are shown surviving in remote, austere conditions. Thought of by this author as embarrassingly lame and unrealistic, it seems to focus on egos and testosterone more than realistic survival scenarios but does give some interesting glimpses into survival psychology.
Survivors – A 1975–77 and 2008 BBC series about a group that survives a horrible plague.
Threads – A grim 1984 BBC TV movie about a couple of families and politicians in Sheffield as they deal with nuclear war.
Fallout (1997) – This video game classic uses a protagonist who has survived nuclear holocaust in the government shelters (the Vaults) and is forced to leave the safety of the vault to find a replacement chip vital to its water recycler. Fallout 2 and Fallout 3 are now available.
“Year Zero”, Nine Inch Nails (2007) – An interesting album with references to a future dystopia that resulted from events and policies of the present.
