Part of Game of Thrones featuring Emilia Clarke, Kit Harington, Peter Dinklage, Lena Headey, and Nikolaj Coster-Waldau.
Rise to Fame
He started acting at 11 to get over shyness, trained at the Royal Conservatoire of Scotland, and reportedly spent nearly a year broke and unemployed before landing Robb Stark in Game of Thrones. The role made him a household name, but it also made him easy to dismiss as a fantasy TV guy. He avoided that by walking away from the show entirely when Robb got killed at the Red Wedding, one of the most talked-about moments in the series.
In the Spotlight
The BBC thriller Bodyguard in 2018 was his real defining moment. Six episodes, one cop with PTSD guarding a politician he despises, and suddenly Madden had a Golden Globe and a Time 100 spot. He went on to play Ikaris in the MCU's Eternals and headline Citadel, Amazon's $300 million spy series that critics met with a shrug. The budget didn't save it, and the show's troubled second season became its own tabloid story.
Side Notes
He has a natural white streak in his hair called a mallen streak, a hereditary condition called poliosis. He dyes it for most roles. Born in Elderslie, Scotland, he stayed close to his working-class roots and regularly returns home. He's private about relationships and rarely comments on tabloid speculation. In 2019, his alma mater gave him an honorary doctorate. The contrast between his polished screen image and his deliberately understated public persona is part of the brand.
