'Harry Potter' role didn't satisfy me: Actress who portrayed 'McGonagall'

English veteran actress Maggie Smith has revealed that although she is "deeply grateful" for her roles in TV series 'Downton Abbey' and 'Harry Potter' films, but "it wasn't what you'd call satisfying". "I didn't...feel I was acting in those things," the two-time Oscar-winning actress said. She further revealed that it thrills her five grandchildren that she did 'Harry Potter' films.
