Bad news for everyone who was anticipating Meryl’s stage reading of Alan Alda’s “Marie Curie” play. According to Entertainment Weekly, Maggie Gyllenhaal will play Nobel-winning scientist Marie Curie in a special reading of Radiance: The Passion of Marie Curie, taking over for Meryl Streep, who had to bow out due to a scheduling conflict. Streep’s spokesperson said in a statement that the two-time Oscar winner was “very disappointed to miss this important and inspiring event.” Gyllenhaal joins the all-star cast of Radiance, which also includes Amy Adams, Bill Camp, Allison Janney, David Morse, Liev Schreiber, and Brent Sexton. Written by Alan Alda and directed by Bob Balaban, the reading anchors the 2011 World Science Festival Opening Night Gala Celebration on June 1 at Lincoln Center’s Alice Tully Hall.
