Chelsea Halfpenny
Halfpenny's professional acting career began in 2004 when she appeared in "Casualty" episode ""What Parents Do"", playing an eleven-year-old girl called Karine.
Imogen Poots
Poots first appeared on-screen in an episode of "Casualty" and had a non-speaking role in "V for Vendetta", but she was largely unknown when, at the age of 17, Juan Carlos Fresnadillo cast her in "28 Weeks Later". Since then, she has appeared in films such as "Cracks", "Centurion", and as the female lead in the 2011 remake of "Fright Night" alongside Anton Yelchin. Although Poots has never formally trained as an actress, according to Giles Hattersley, she developed her acting skills through a practical apprenticeship that may have served her well, as she is "compellingly natural" in front of the camera.
