( EW.com ) -- Fox 's Batman prequel `` Gotham '' has filled four major roles , including The Penguin and Alfred Pennyworth . The following actors will join star Ben McKenzie ( `` Southland '' ) as Det . Gordon in the pilot : . • Robin Lord Taylor as Oswald Cobblepot ( a.k.a . the Penguin ) . He 's described as having `` the brains of a chess grandmaster and the morals of a jackal , Oswald Cobblepot is a low-level psychopath for gangster Fish Mooney who hides his sadistic lust for power behind an exquisitely polite demeanor . '' Taylor had appearances on several shows , most notably on AMC 's `` The Walking Dead '' during season 4 , playing a survivor named Sam who runs into Rick and Carol . 'Game of Thrones ' star joins Fox 's '24 ' in major role . • Next is Zabryna Guevara ( `` Burn Notice '' ) as Captain Essen : `` Gordon 's boss at the GCPD Homicide Squad , Captain Essen balances the two worlds of police and politics with a Machiavellian skill that 's as much corporate litigator as cop . '' • Sean Pertwee ( `` Event Horizon '' ) as Alfred Pennyworth : `` A tough-as-nails ex-marine from East London , Alfred Pennyworth has loyally served the Waynes . Now , in the wake of their tragic deaths , he 's fiercely protective of the young Bruce Wayne . '' • Erin Richards ( `` Being Human '' ) as Barbara Kean : `` A sophisticated emergency room doctor , Barbara is the fiancée of James Gordon , joyful but with an edge of vulnerability . She stands by her future husband ... which can be difficult in a world as corrupt as Gotham . '' Death Watch 2014 : TV show survival predictions . `` Gotham '' is billed as an origin-story prequel series to the Batman films from Warner Bros. TV . Bruno Heller ( `` The Mentalist '' ) wrote the pilot script and will serve as executive producer . Danny Cannon ( `` Nikita '' ) will direct and executive produce the pilot . Thoughts ? Those descriptions are pretty intriguing . Love the idea of Alfred as a tough solider rather than merely a genteel butler ( the DC Comics have a few different versions of Alfred 's backstory , but one is that he 's a retired intelligence agent ) .
