Margaret Rose Mount OBE (2 May 1915 – 13 November 2001) was an English actress. As a child, she found acting an escape from an unhappy home life. After playing in amateur productions, she was taken on by a repertory company and spent nine years in various British towns, learning her craft. In 1955, she got her big break in the comic play Sailor Beware!: she created the leading role in a repertory production and, though unknown to London audiences, was given the part when the play was presented in the West End. She became known for playing domineering middle-aged women in plays, films and television shows.
