The film Florence Foster Jenkins is one of Charles' upcoming projects (ambitionmakesmetired via hellyescharlesedwards). It stars Meryl Streep as Jenkins and Hugh Grant as St Clair Bayfield. Jenkins was a socialite who dreamt of becoming a great opera singer and Bayfield was her manager. When Florence decided to give a public concert at Carnegie Hall in 1944, St. Clair knew he faced his greatest challenge - protecting her from the fact that her singing was actually awful (BBC Films).
Director Stephen Frears previously worked with Charles on Philomena.
