Amy Nuttall, 'Downton Abbey'
You know her as: Downton Abbey housemaid Ethel Parks / Why we like her: Nuttall proved that you don't need to go overboard to have a dramatic storyline be extremely effective. Ethel Parks' tale in Season 3 was understated yet very significant in revealing underlying complexities of key characters and relationships this past year. Though it wasn't an easy role to play, Nuttall made it seem effortless. / Where else you've seen her: Melanie Hughes on "Hotel Babylon" and Chloe Atkinson on "Emmerdale."
