The 78-year-old actress, who portrays Lady Grantham in the popular PBS series, told "60 Minutes" that she hasn't watched the drama because doing so would only make her agonize over her performance. She said she may watch it someday.
Smith told Steve Kroft, in an interview to be televised Sunday, that what she takes from the role is "the delight of acting."
She has three Oscars, two Emmys and a Tony Award, but said the "Downton Abbey" role has given her more public recognition than anything in her career.
