The 100 (pronounced The Hundred ) is an American post-apocalyptic science fiction drama television series that premiered on March 19, 2014, on The CW. The series, developed by Jason Rothenberg, is loosely based on the novel series of the same name by Kass Morgan.
The series follows a group of post-apocalyptic survivors, chiefly a group of adolescents, including Clarke Griffin (Eliza Taylor), Bellamy Blake (Bob Morley), Octavia Blake (Marie Avgeropoulos), Jasper Jordan (Devon Bostick), Monty Green (Christopher Larkin), Raven Reyes (Lindsey Morgan), Finn Collins (Thomas McDonell), John Murphy (Richard Harmon), and Wells Jaha (Eli Goree). They are among the first people from a space habitat, “the Ark”, to return to Earth after a devastating nuclear apocalypse. Other lead characters include Dr. Abby Griffin (Paige Turco), Clarke’s mother; Marcus Kane (Henry Ian Cusick), a council member on the Ark; and Thelonious Jaha (Isaiah Washington), the Chancellor of the Ark and Wells’s father.
