Sullivan Stapleton (born 14 June 1977) is an Australian actor who is best known for his roles in the SKY (BSkyB)/Cinemax/HBO television series Strike Back, Animal Kingdom and 300: Rise of an Empire. He is currently starring in the NBC crime drama Blindspot which premiered on September 21, 2015.Stapleton played the lead role, Greek leader Themistocles, in the film 300: Rise of an Empire (2014). He was honoured on 24 October 2013 with a Breakthrough Award at an exclusive Australians in Film Benefit Dinner held in Los Angeles. Stapleton was born in Melbourne, Victoria. He was eight years old when he and his younger sister, actress Jacinta Stapleton, six at the time, joined an acting and modelling agency. The idea first came to their aunt who signed her kids with the agency. She then asked her nephew and nieces if they would like to join and their mother signed them in. Stapleton's younger brother Joshua Stapleton also launched into acting in early childhood following his brother's footsteps yet along with pursuing talents in Dance and Musical Theatre. His picture caught the attention of a director who then invited him to be in his short film (about high school dropouts at a party where girls were dying, without the graphic violence). Pleased by his performance, the director qualified him as gifted and encouraged him to pursue acting. Stapleton received training at Melbourne's St. Martin's Theatre. He studied drama and theatre at Sandringham Secondary College (in Sandringham, Victoria, Australia). He launched his career in Australia. He got his actors' union card at the age of 9 (in 1986) and at the age of 11 he started working in ads. His first onscreen acting performance was in the 1994 Australian TV-movie Baby Bath Massacre as Adrian. Between acting jobs, Stapleton did several types of work: modeling, cleaning animal cages in a pet shop, working as a grip (taking care of the camera equipment) in a considerable number of films and TV productions (The Elephant Princess, Rush, Tangle) in front and behind the camera, working on building sites, and assisting carpenters. Before landing a role as Josh Hughes in Australian soap opera Neighbours in 1998, he appeared in a string of little-seen features and homegrown dramas. Other notable roles include Justin Davies in the Australian televised serial The Secret Life Of Us (between 2003 and 2005), Fearless in the motion picture December Boys (released in 2007), special agent Wilkins in the mainstream feature, The Condemned (an American action film distributed in 2007). But it was with Stapleton's performance in the Academy Award nominated film Animal Kingdom, which premiered at the 2010 Sundance Film Festival, that he made an international breakthrough.
