The Crown season 3 trailer: Fans spot mistake in line about the Queen's Silver Jubilee in Netflix show

Netflix has finally gifted The Crown fans with a full trailer for its much anticipated third season.

The trailer provides fans with a first full look at Olivia Colman as Queen Elizabeth and Helena Bonham Carter as Princess Margaret. Queen Elizabeth was previously played by Claire Foy and Princess Margaret by Vanessa Kirby.

Superfans of the Royal Family not only noticed that Colman’s eyes are brown instead of blue, like Queen Elizabeth, but a slight error in dates.During the trailer, a radio announcer states “This is Jubilee day. This is a day as grueling as the Queen's coronation 25 years ago."

The Queen’s Jubilee was in 1977, which was actually 24 years after her coronation, but 25 years after she ascended to the throne.

Queen Elizabeth’s father, King George VI, died in February of 1952 which led to the Queen’s immediate accession of the throne. This means that her Jubilee celebration took place 25 years after her accession to the throne rather than 25 years after her coronation date.

The Crown’s season 3 is set to premiere on November 17, 2019, on Netflix.

Meanwhile filming continues on season 4, which will see Emma Corrin play Princess Diana and God's Own Country star Josh O'Connor play a young Prince Charles. Both actors were spotted in character recently filming Australia tour and polo match scenes in Spain.
