Magpie is played by actress Marié Botha, who is a relative newcomer to film and television, in The Penguin. Botha's primary credits to this point are in short films, but she did also guest star in an episode of Apple TV+'s Dickinson alongside Hailee Steinfeld and play a leading role in the 2022 feature film Highway One.

Matt Reeves is keen to ensure that the Batman universe has exciting DC villains before the second film comes out.

The Penguin gave a small role to an obscure Batman villain from the pages of DC Comics, the crazed jewel thief known as Magpie.
