Producer David Heyman calls Leta Lestrange, played by Zoe Kravitz, one of the film's most "fantastic" new characters. "She's complex and rich and charismatic," he said. "Zoe is bringing colour and shade to the part that, I think, elevates it even further. She is a wonderful character, who is, like so many of Jo's characters, sort of trying to come to terms with who they are."
