Richard Scott Harmon, born on August 18, 1991, is a Canadian actor who has carved a distinctive path through television and film with a series of compelling, often morally complex performances. He is perhaps best known to international audiences for his portrayal of the volatile and tragic John Murphy on the long-running post-apocalyptic series The 100, a role that evolved from a despised antagonist into a fan-favorite antihero over the show’s seven-season run from 2014 to 2020. Harmon’s ability to imbue his characters with a raw, unpredictable energy has made him a sought-after talent in the science fiction and drama genres, earning him a reputation as an actor unafraid to explore the darkest corners of the human psyche.

Harmon began his acting career in his native Canada, landing early television roles that showcased his range. He gained significant attention for his portrayal of Jasper Ames in the first two seasons of the acclaimed AMC crime drama The Killing from 2011 to 2012, where he played a troubled teenager at the center of a murder investigation. He soon followed this with a leading role as Julian Randol, a charismatic but dangerous cult leader, on the time-travel science fiction series Continuum from 2012 to 2015. These early performances established Harmon as a performer capable of handling intense, dramatic material, setting the stage for the breakout role that would define his career.

While his television work brought him widespread recognition, Harmon also demonstrated his dramatic depth on the big screen. He received critical praise for his leading role in the 2013 independent film If I Had Wings, a touching drama about a blind teenager who dreams of running in the Olympics. The role showcased a more vulnerable and inspiring side of the actor, proving he could carry a film with emotional subtlety. In 2025, he returned to the horror genre with a supporting role in Final Destination Bloodlines, the latest installment in the long-running franchise, playing the character Erik Campbell. Looking ahead, Harmon is set to star in the upcoming series Memory of a Killer in 2026, playing the role of Joe, ensuring his continued presence on screen as he takes on new and challenging projects.
