Louis got his first break when he was burnt alive by a dragon in Games of Thrones (credited role). He rose from the ashes to perform in Jesus Christ Superstar. He was then cast in the BBC series Hope Street, as Shay, a cheeky but lovable returning character. This was followed by the feature film Silent Roar, where Louis was the lead. Stranger Things, The First Shadow, the stage play on London's West End, came calling and cast Louis as the lead, Henry Creel, which landed him numerous awards and nominations. Louis was then invited to reprise his lead role in Stranger Things for the Broadway production, which saw him nominated for a Tony Award, as Best Leading Actor in a play.
