Directed by David Blair and written by Neil McKay, the series will tell the story of Anthony Walgate, Gabriel Kovari, Daniel Whitworth and Jack Taylor, who were all murdered by Port between 2014 and 2015.
Port met his victims online (including gay dating app Grindr) before leading them to his home in Barking, London where they were given lethal doses of a date rape drug and raped.
In 2016, he received a life sentence with a whole life order, meaning he will die behind bars. Utilising “extensive research and multiple sources” to ensure the series is as accurate as possible, Four Lives stars Stephen Merchant as Port and Sheridan Smith as Sarah Sak, the mother of the late Walgate.
