For Kaley Cuoco, who voices the titular anti-hero, finding the right tone and character for her version of Quinn was harder than she initially thought, with the actor eventually heading back to re-record earlier dialogue after discovering right balance later on in production.
"After a few weeks, it became more manic and hysterical, so I wanted to go back and re-record [the earlier episodes] to make sure it was just as badass from the beginning," Cuoco told TVLine. "I think with any character, especially when on a new show, it takes some getting used to. I've perfected certain looks and facial expressions over the years, so this in a way was harder — also because I'm voicing someone as iconic as Harley. And also, my voice is very recognizable, so I didn't want to force an accent or try to be someone I'm not. I'm 'Kaley as Harley,' and accepting that early on enabled me to me free and very authentic."
DC Universe's Harley Quinn stars Kaley Cuoco, Lake Bell, Diedrich Bader, Alan Tudyk, Rahul Kohli, Christopher Meloni, Tony Hale, Ron Funches, Wanda Sykes, Natalie Morales, Jim Rash, Giancarlo Esposito, Jason Alexander and J.B. Smoove. The series premieres on Nov. 29.
