Alain Moussi is an international action star born on March 29, 1981 in Libreville, Gabon from a Lebanese father, Jean Moussi, and French-Canadian mother, Rita Moussi. Moussi began his martial arts training in the art of jujutsu under Canadian martial arts legend John Therien and also trained in kickboxing under legendary kickboxing champion Jean-Yves Theriault. He had trained in Brazilian jiu-jitsu under Carlos Machado, eventually earning his black belt in the art. Moussi got his start as a stuntman and credits Jean Frenette, a former world martial arts champion turned stunt coordinator for films, with giving him his start. His first job was doubling Henry Cavill in the film Immortals. He has doubled for Travis Fimmel in Warcraft, Hugh Jackman in X-Men: Apocalypse, and Jai Courtney in Suicide Squad.

At the Cannes Film Festival in 2014, it was announced he would get his first lead role in a reboot of the 1989 film Kickboxer, which starred Jean-Claude Van Damme. In Kickboxer: Vengeance, Moussi played Kurt Sloane, a young martial artist who must refine his skills to avenge his brother's death. Van Damme himself replaced the departing Tony Jaa as Kurt's teacher, now named Master Durand. The film received mixed reviews but the confidence of the film resulted in two sequels, Kickboxer: Retaliation, released in 2017, and Kickboxer: Syndicate, which began production in February 2017. The sequels bring Moussi back as Kurt Sloane and in addition, Moussi and longtime friend Jean-Francois LaChappelle served as fight choreographers of Retaliation.

Moussi also played the role of Charlie Nash in the web series sequel Street Fighter: Resurrection.
