The actress is in talks to reteam with Mamma Mia! director Phyllida Lloyd for Thatcher, a biopic of the former British prime minister. The movie will be focused on Thatcher’s attempts to save her floundering career in the 17 days preceding the Falklands War in 1982. Jim Broadbent is in talks to play Thatcher’s husband, Denis. With this and last week’s announced collaboration with Jeff Bridges and Mike Nichols, it looks like Streep’s biggest competition in the 2012 Oscars may be herself. [HR]
