O diretor recentemente explicado :
David Ayer recently opened up regarding the iconic psycho's "damaged" tattoo, and how it specifically relates to the death of Jason Todd a.k.a Robin. He elaborated:
This is sort of my personal thing and maybe less about a larger connection. But Joker killed Robin and Batman basically smashes his teeth out and locks him up in Arkham Asylum. It's in the asylum where Joker would have done the 'damaged' tattoo as a message to Batman saying, 'You've damaged me. I was so beautiful before and now you've destroyed my face.' That's where the grill comes from.
David Ayer falou com Empire e explicou que os dentes metálicos do The Joker e sua tatuagem "danificada" têm raízes no enredo de Batman em Death in the Family .
