Michelle Dockery is back in another period drama – but she has swapped 1920s high society for the two-tone music scene of the 80s. In BBC drama This Town – from the pen of Peaky Blinders creator Steven Knight – Michelle plays Estella, a mother and singer who never hit the big time, due to her difficult relationship with alcohol. Against a background of social unrest and IRA terrorist threats, a group of young people harness the power of music to escape their grim reality.
