The three-part series explores the real life events surrounding the evil Rochdale grooming gang which carried out assaults on dozens of young girls.
Lisa, who plays one of the victims' mothers, Lorna, in the BBC show, revealed how she battled with the horrific storyline, telling the ITV panel: "I got angry and I got more angry". I'm ready to start to live my life again where I haven't been for such a long time.
"Mine's been digitally enhanced", Lisa joked about her chest to her fellow panellists. I feel confident our drama doesn't really give them much opportunity to do so. Why am I feeling so angry?'
"But the real life me, and the real life Liv (Hill's) character (Ruby Bowen), was there behind the monitor".
Lisa's voice trembled as she recalled: "I remember the day when we met with the director and the phenomenal team, and when you read the script and every word is true..."
"Getting the justice out there, it was wonderful I was able to portray that", she added.
