Merle Streep sings badly in the new film Florence Foster Jenkins, based on a NYC heiress and arts patron who performed arias and art songs totally off key, but made recordings and performed at Carnegie Hall. Streep is actually a very good singer which she's shown in previous films.
Meryl Streep won a Golden Globe for her performance as Margaret Thatcher in The Iron Lady. She talks about preparing for that role, her other films and how her perceptions of herself have changed over the years.
