While we await the release of the third season of Netflix’s The Crown, filming has already begun on the fourth.

Production began yesterday (19th August) on the drama’s fourth outing with the production based at its usual home of Elstree Studios.

The fourth season is expected to focus on the Diana years, as it moves towards the backdrop of the 1980s with Emma Corrin lined up to play the late princess.

Gillian Anderson is also on board to play Margaret Thatcher.

There are expected to be at least another two series after this one, totalling a possible 60 episodes; the first run of ten episodes reportedly cost around £100 million to make.

Netflix finally released a trailer for the third season just last week.
