The Penguin star Deidre O'Connell says she felt a responsibility when playing Francis Cobb, the mother of Colin Farrell's titular villain.
"I know more about it than I would like to know about it because my dad had it and my mom’s got it. I felt a responsibility to talk about that in being Francis. I was lucky enough to find a PT nurse for Parkinson’s who let me into their homes to watch them doing their PT sessions," O'Connell revealed at a New York City Comic Con roundtable attended by GamesRadar+. "I unfortunately also know a bunch of people with Parkinson’s, so I knew the feel of that, I knew the feel of everybody. I just felt a huge responsibility to not ever soft-sell it, but not be showy with it, and give her the dignity of being someone who did not want people to know about it and did not want to be in this situation and was not playing the dependence card at all."
