Matt Reeves’ The Batman was a smash success last year and now the franchise is slowly expanding with a limited series surrounding the Penguin, portrayed by Colin Farrell, on HBO Max.

Three new cast members have been added to its expanding ensemble; Shohreh Aghdashloo, Deirdre O'Connell and Michael Kelly. Character details are currently under wraps for the time being. Aghdashloo is best known for her roles in The Expanse, House of Sand and Fog, and The Stoning of Soraya M. Meanwhile, O'Connell has starred in The Boy Downstairs, Cool World, Diane, and recently won a Tony award for her performance in Dana H. Finally, Kelly has recently appeared in House of Cards on Netflix and Jack Ryan on Amazon Prime.

The eight-episode limited series will star Colin Farrell, who reprises his role as Oswald “Oz” Cobblepot from The Batman. The cast currently consists of Farrell, Aghdashloo, O’Connell, Kelly, Cristin Miloti and Rhenzy Feliz.
