The cast of HBO Max’s Penguin series is growing ahead of its production start date.

Michael Kelly, Shohreh Aghdashloo, Deirdre O’Connell and Rhenzy Feliz have joined the cast of HBO’s The Batman spin-off series about The Penguin. Details regarding the roles of the first three actors are being kept under wraps, but Feliz is said to be playing the driver of the titular DC Comics villain.

Also known as Oswald “Oz” Cobblepot, The Penguin is one of Batman’s most notorious foes. He’s a master criminal with a distinctive look, thanks to his rotund physique, top hat, monocle and long nose. He’s been portrayed on-screen before by actors like Burgess Meredith, Danny DeVito and Robin Lord Taylor, but Colin Farrell is the latest star to bring him to life.
