Actress Meryl Streep talks about about starting out, her ‘technique’, making “Sophie’s Choice” (1982), working with De Niro, Nicholson and Hoffman, why she did "The River Wild” (1994) and “The Bridges of Madison County” (1995), always being asked about accents, the success of “The Devil Wears Prada” (2006) and “Mamma Mia!” (2008), and why women often see potential where men do not.
