Tom Hanks and Tommy Lee Jones are also reportedly in talks to play Lyndon B. Johnson and Richard Nixon, respectively, while Emily Watson is attached to play the formidable Margaret Thatcher. Director Krishna Shah calls it "the project of my life" so one hopes this could actually come together for him with this kind of cast. The film is scheduled to be released in 2010, which seems a bit too optimistic with so many schedules to coordinate, but we'll see.
Obviously, this should be filed firmly under "rumor," but it's an intriguing prospect. Indira Ghandi is certainly long overdue for a biopic, and the cast would be fantastic. It would be fascinating to see Mirren go back and play a younger Queen Elizabeth II, even for just a small part in a larger historical picture. Besides, with Michael Sheen doing triple duty as Prime Minister Tony Blair, it seems very appropriate that his onscreen monarch get another shot at the throne.
