In "The Proposal", what is the name of Sandra Bullock's character?

In "The Proposal," Sandra Bullock plays Margaret Tate. Margaret is a demanding New York book editor whose professional authority hides the precariousness of her immigration status.

When Margaret learns that she may be deported to Canada, she claims that she is engaged to her assistant, Andrew Paxton, played by Ryan Reynolds. Andrew agrees to the arrangement only after Margaret promises to promote him, and the pair travel to Alaska to meet his family.

The fake engagement supplies the film’s comic engine, but the story gradually shifts as Margaret becomes more involved with Andrew’s family and begins questioning the lonely, controlling life she has built in New York. The contrast between Margaret’s intimidating office persona and her awkwardness around the Paxtons drives many of the film’s memorable scenes.

The other options are not Sandra Bullock’s character: Sarah, Annie, and Lucy are unrelated names in this question. The 2009 romantic comedy was directed by Anne Fletcher and became one of Bullock’s notable commercial successes, pairing her with Reynolds before their later work in other genres.
