She is soon to star in the independent feature She Will opposite Rupert Everett. Bacon most recently completed production on season two of the FX/Avalon series Breeders, in which she plays Martin Freeman’s mother.

Most recent TV credits include BBC Three’s hugely popular sitcom Him & Her, ITV’s Prime Suspect 1973 and ITV’s Cradle to Grave.
