Four Lives, previously titled The Barking Murders, was filmed in 2019 and had been due for release in 2020. The release has been delayed due to inquests.
Four Lives cast
Stephen Merchant (Fighting With My Family, Extras, The Office) will play Stephen Port, and Sheridan Smith (The Moorside, Care, Mrs Biggs) will play Sarah Sak, the mother of Anthony Walgate.
Also joining the cast is Jaime Winstone (Five Daughters, Babs) as Donna Taylor, one of the sisters of Jack Taylor.
Stephen Merchant said: “This is a story that can’t be ignored - how four young lives were lost and their families’ brave attempt to uncover what happened. This factual drama will shed light on their story, so it’s a privilege to be a part of telling it with the brilliant combination of Jeff Pope, Neil McKay and the BBC.”
Sheridan Smith added: “I love playing real life characters - especially an inspirational woman like Sarah Sak - but with it comes responsibility.
"Along with the other families, Sarah went through so much heartache and it would have been easy for her to just accept what she was being told by the police, but something inside made her keep fighting for her son.”
