British newspaper The Sunday Times has claimed Gillian Anderson will portray PM Margaret Thatcher in The Crown.
But some reports suggest the deal is not yet done, with The Hollywood Reporter noting negotiations have been underway since April.
It is unclear if Anderson would appear as Thatcher solely in Season 3 —the first to feature Olivia Colman as Queen Elizabeth II— or recur through Season 4.
Netflix is yet to confirm the casting.
