The Hollywood actress is said to be in negotiations to re-team with her Mamma Mia! director Phyllida Lloyd for the 1982-set film, which will show Thatcher in the run-up to the Falklands War.
Moulin Rouge! actor Jim Broadbent has reportedly been lined up to play the former British leader’s husband, Denis, according to the Hollywood Reporter.
Thatcher led Britain for 11 years between 1979 and 1990. Her career famously waned prior to the conflict in the Falklands but she received a boost in popularity after the 72-day war, which saw her triumph in the U.K.’s 1983 election.
