The 100 is a post-apocalyptic science fiction action television series, based on the book series of the same name by Kass Morgan. The series aired on The CW from March 19, 2014, to September 30, 2020, having aired 100 episodes over seven seasons.

On April 24, 2019, the series was renewed for a 16-episode seventh season, which was announced to be the series' last in August of that year.

Summary

The series is set 97 years after a devastating nuclear apocalypse wiped out almost all life on Earth. Over 2,400 survivors live on a single massive station in Earth's orbit called "The Ark". After the Ark's life-support systems are found to be failing, 100 juvenile prisoners are sent to the surface in a last attempt to determine whether Earth is habitable. They discover that not all humanity was wiped out, and some survived the nuclear apocalypse: the Grounders, who live in clans locked in a power struggle; the Reapers, another group of Grounders who have become cannibals; and Mountain Men, who live in Mount Weather and locked themselves away before the apocalypse.

In the second season, the remaining 48 of the 100 are captured and taken to Mount Weather by the Mountain Men. It is eventually revealed that the Mountain Men are transfusing blood from imprisoned Grounders as an anti-radiation treatment. Medical tests of the 100 show an even more potent anti-radiation efficacy; their bone marrow will allow the mountain men to survive outside containment. Meanwhile, the inhabitants of the Ark have successfully crash-landed various stations on Earth and begun an alliance with the Grounders to save groups of people, naming the main settlement at Alpha Station "Camp Jaha".

In the third season, Camp Jaha, now renamed "Arkadia", comes under new management when Pike, a former teacher and mentor, is elected as chancellor and begins a war with the Grounders. An artificial intelligence named A.L.I.E. was revealed to be responsible for the nuclear apocalypse that devastated Earth 97 years ago, and she takes over the minds of nearly everyone in Arkadia and Polis, the capital city of the Grounders. In the season three finale, Clarke manages to destroy A.L.I.E.

In the fourth season, hundreds of nuclear reactors around the world are melting down due to decades of neglect, again making Earth uninhabitable. Clarke and the others investigate ways to survive the coming wave of radiation. When it is discovered that Nightbloods, descendants of first, original Nightbloods, including Becca, the first Commander and creator of A.L.I.E., are immune to the effects of radiation, Clarke and the others attempt to recreate the formula, but their attempts failed. An old bunker is discovered that can protect 1,200 people for over 5 years; each of the twelve clans select a hundred people to stay in the bunker. A small group decides to return to space and survive in the remnants of the original Ark.

Production

Development

Post production, including ADR recording for the series, was done at the recording studio Cherry Beach Sound.

David J. Peterson, who created Dothraki for Game of Thrones, developed the Trigedasleng language for The Grounders. Jason Rothenberg said it was similar to Creole English.

After his constructed language work on Star-Crossed, Peterson was contacted by the producers of The 100 to create a language for the Grounders, an evolution of English. In the setting, around 250 years have passed since the apocalypse, which is a very short time for significant language change. Because of this, Peterson posited an accelerated evolution in which the early Grounders used a cant specifically to obfuscate their speech and to differentiate between friend or foe. Trigedasleng derives from that cant and evolved over several short generations of survivors of the apocalypse.

Filming

Filming for the series takes place in and around Vancouver, British Columbia. Production on the pilot occurred during the second quarter of 2013. After the show was picked up to series, filming occurred for the first season between August 2013 and January 2014. Filming for the second season commenced on July 7, 2014, and concluded on January 23, 2015. The third season was filmed between July 15, 2015, and February 2, 2016. Filming for the fourth season commenced on August 2, 2016, and concluded on January 18, 2017. Filming for the fifth season commenced on August 14, 2017, and wrapped up on January 27, 2018.

Casting

In late February 2013, Bob Morley and Eli Goree were cast as Bellamy Blake and Wells Jaha, respectively, followed a day later by the casting of Henry Ian Cusick as Marcus Kane. Less than a week later, Eliza Taylor and Marie Avgeropoulos were cast in co-starring roles as Clarke Griffin and Octavia Blake, respectively. Throughout March, the rest of the cast was filled out, with Paige Turco cast as Abigail Walters (now Abigail Griffin), Isaiah Washington as Chancellor Jaha, Thomas McDonnell as Finn Collins, Kelly Hu as Callie Cartwig, and Christopher Larkin as Monty Green.

For the second season, Adina Porter and Raymond J. Barry were cast in recurring roles as Indra and Dante Wallace, respectively, along with Alycia Debnam-Carey as Lexa.
