Fresh off a breakout role in Netflix comedy Sex Education, Gillian Anderson may be putting her British accent to use once more. Season 3 of The Crown is reportedly in final negotiations to feature Anderson in the key role of British prime minister Margaret Thatcher, in what may become a two-season arc.

British newspaper The Sunday Times claimed Anderson’s casting as a done deal, while The Hollywood Reporter adds that negotiations have been ongoing since April of 2018. Netflix declined comment, and it is unclear if Anderson would appear as Thatcher solely in Season 3—the first to feature Olivia Colman in the aged-up role of Queen Elizabeth II—or recur through Season 4, which follows the same 1960s-1970s stretch of her reign.

It’s worth noting that Thatcher first became leader of England’s Conservative Party in 1975 and was elected as prime minister in 1979, leaving it unclear which stage of her career The Crown might feature. The so-called “Iron Lady” has been depicted a number of times onscreen throughout the years, perhaps most visibly by Meryl Streep in the Oscar-winning 2011 film of the same name. Thatcher passed away of a stroke in April 2013.

Netflix has also not confirmed a premiere date for The Crown Season 3, beyond the expectation of debuting it in 2019. In addition to Colman taking over the lead role from Emmy and Golden Globe-winner Claire Foy (Colman also recently won a Globe for The Favourite), the next Crown leg will feature Tobias Menzies taking on the role of Prince Philip from Matt Smith, and Helena Bonham Carter replacing Vanessa Kirby as Princess Margaret.
