Boyle was familiar with the landscape and history depicted in Say Nothing, saying "the streets we were walking down were streets I’ve walked my whole life." His school was located on the Falls Road, just down the street from a mural of Brendan Hughes, whom he portrayed in the show. Co-star Lola Petticrew described Boyle as "one of [their] best friends in the world" since they were age 11. Boyle is also a longtime friend of Frank Blake, who portrayed Seamus Wright.[7]
