Born in 1980, fair-haired British actress Sinead Matthews attended London's exclusive Royal Academy of Dramatic Art and thereafter divided her efforts between film, television, and the stage. Theatrically, her efforts include work in productions of The Wild Duck, The Crucible, The Women of Troy (at the National Theatre), and innumerable other plays. On television, Matthews placed her strongest emphasis on small-screen features including Terry Pratchett's Hogfather and Viva Las Blackpool. Matthews took one of her first major big-screen bows with a small supporting turn as one of schoolteacher Poppy's (Sally Hawkins) carefree friends, in Mike Leigh's critically praised seriocomedy Happy-Go-Lucky (2008). ~ Nathan Southern, All Movie Guide
