why she wanted to take the part of Nicci<\/a> at a recent screening and Q&A, Horgan said: \u201cWell, I didn\u2019t want to take part! I was mid-filming Bad Sisters and my agent said, \u2018This script has come in from Jack Thorne,\u2019 and I\u2019d wanted to work with Jack for so long.<\/span><\/p>\n\u201cI was aware that I was mid doing something and it would be filming very soon after it ended, but I had a meeting with Jack and I read it and it just destroyed me.\u201d<\/span><\/p>\nShe continued: \u201cI felt really nervous, to tell you the truth. But then we had a Zoom and I felt a bit less nervous. And I guess I had that feeling, I felt really connected to Nicci, I felt really connected to her point of view. I really felt it deeply and I guess the thought of someone else paying her, I didn\u2019t love.\u201d<\/span><\/p>\nHorgan continued: \u201cI think the thing that I was most scared about \u2014 actually, my daughter\u2019s in the audience, she\u2019s 19, and since she came along I\u2019ve been an emotional wreck. And I was just worried about getting through it, really, and not just going to pieces. And we talked a lot about how you manage that and how you do it.<\/span><\/p>\n\u201cI know a lot of it is hard going and it kind of has to be, but the way Jack and Michael talked about it was how important it was to show them being a family, and the beautiful moments, the light moments and the moments of love, and the joy of that, and it felt like a really great way to approach it.\u201d<\/span><\/p>\nSo, who else is in the cast alongside Horgan and Sheen?
