Meryl Streep took opera singing lessons as a child, and as an adult, she previously sang in several films, including Postcards from the Edge, Silkwood, Death Becomes Her, and A Prairie Home Companion. She was a fan of the stage show Mamma Mia! after seeing it on Broadway in September 2001, when she found the show to be an affirmation of life in the midst of mourning the destruction of the September 11 attacks.
