Imogen Poots (born 3 June 1989) is an English actress. She is best known for playing Tammy in 28 Weeks Later
. 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 the 2011 remake of Fright Night. Although Poots has never formally trained as an actress, according to Giles Hattersley, a practical apprenticeship may have served her well, as she is "compellingly natural" in front of the camera.
