Bunker 6 is a 2013 Canadian psychological thriller film set in an alternate timeline in which a nuclear holocaust takes place during the Cuban Missile Crisis.

On October 30, 1962, young Grace (Sophie Elliott) knows her father (Glenn Lefchak), who is a high-ranking military officer, is afraid that the United States and the Soviet Union are about to unleash nuclear attacks on each other's homeland.

[1] The fallout shelter was constructed in the 1960s and built to house 350 people, but the cast and crew found that working underground in the massive centre for the length of the production was not only claustrophobic but also extremely tiring.

[1] Despite its modest budget and limited use of special effects, many critics found Bunker 6 a refreshing departure from the cookie-cutter school of horror and science fiction films.

Jay Seaver inEFilmCritic.com commented: "... And while I don't particularly like describing a film's location as being like a character, there is no doubt that 'Bunker 6' benefits immensely from being able to shoot in an actual Cold War bunker in Nova Scotia meant to shelter the government in case of nuclear attack.

Jackson and cinematographer Christopher Ball shoot impressively even when the location forces them into odd angles, and get a big boost from some downright fantastic sound work.
