Mark Bonnar worked in Edinburgh City’s libraries and the council’s planning department before committing to a career in acting. He graduated from the Royal Scottish Academy of Music and Drama (now the Royal Conservatoire of Scotland) in 1996. Much of his early career focused on theatre roles. In order to spend more time with his young children, he began seeking out more screen work and in 2013, he appeared in the popular crime drama Shetland. The following year, his role in the successful BBC show Line of Duty earned him his first BAFTA Scotland nomination, an award which he won in 2017 for his performance in the crime drama Unforgotten. Other successful shows have included Catastrophe (2015-19), Humans (2018), Summer of Rockets (2019) and Guilt (2019).
