Characters of Casualty
Pauline "Polly" Emerson, portrayed by actress Sophia Di Martino from 2009 to 2011, is an ambulance technician. She's described by the BBC as: "a superhero; she wants to save the world. The only problem is Polly is young, idealistic and needs to learn that the world is a complicated place and not everyone wants to be healed." Di Martino had previously appeared in supporting roles in both "Casualty" and spin-off "Holby City". She auditioned three times for the part, and had to cease studying for her Masters degree in Applied Theatre when cast. She commented on her casting: "I feel very lucky to be joining such a long-running and well-established drama. I'm looking forward to Polly bursting onto screens, and hope viewers find her as much fun as I do." Series producer Oliver Kent added: "Sophia is a brilliant actress and we're very excited that she's joining us. We can't wait for the audience to see her - they're going to love her." Di Martino describes Polly as "very optimistic. She sees the best in everyone. She's fun, opinionated, brave and sometimes gets a little bit too close to her patients." After the suicide of homeless man Alistair MacCormack, who was infatuated with Polly, Polly was suspended while a full inquiry into his death was undertaken, after evidence given against her by Alistair's best friend, Abe, who believed that Polly should lose something that she really loved - her job - as revenge.
