Meryl Streep's musical abilities take a purposeful turn for the worse in "Florence Foster Jenkins." The triple Oscar-winner portrays the real-life title character, a World War Two-era New York socialite whose passion for music far outweighed her singing skills. The movie, opening in U.S. movie theaters on Friday, follows Jenkins around 1944 as, at age 76, she prepares for her first big public performance at a sold-out Carnegie Hall.
