Playing real people is a privilege. It's important to me that I do Ann justice

SHERIDAN SMITH STARS IN THE TRUE STORY OF A MUM WHO FOUGHT TO ENSURE HER CHILD'S KILLER PAID FOR HIS CRIME. BY LYNN RUSK

"Playing real people is a privilege, and it's why I do what I do," says Lincolnshire-born Sheridan

"I instantly knew that I had to play Ann because of her story, her resilience, her strength, and everything she went through to fight an 800-year-old law. She just wouldn't give up."

The 44-year-old TV and stage star, who has previously played a mother who loses a child, says the experience this time felt very different because she is now a mother herself.
