Actor Maxine Peake "gave the performance of a lifetime" when playing a Hillsborough justice campaigner in a TV drama, the show's creator has said.
Anne Williams dedicated her life to uncover what happened to her son Kevin, who died aged 15 in the 1989 tragedy.
The four-part ITV series, titled Anne, reveals her fight for justice for the 97 victims before she died in 2013.
Writer Kevin Sampson said the drama was part of an "on-going education" on what can be learned from similar atrocities.
He was assisted by Mrs Williams's daughter, Sara, in creating the drama which concludes later.
