Princess Diana's royal love story comes crashing down in 'The Crown' season 4 teaser

The recently-dropped teaser for season 4 of Netflix series The Crown features a devastated Princess Diana whose royal love story crumbles to pieces unexpectedly.

Emma Corrin, who essays the magnanimous role of Diana in the season, can be seen bearing an uncanny resemblance to the late royal while taking the viewers through a tumultous journey of her marriage with Prince Charles. 

Right from the days of their glimmering courtship, a public wedding for the ages and a dramatic separation, the teaser shows how the biggest royal wedding of the decade reached its tragic end. 

The teaser begins with the narrator saying, "Here is the stuff of which fairy tales are made.”

The season chronicles the era from 1979 to 1990 and will again feature Olivia Colman as Queen Elizabeth, Helena Bonham Carter as Princess Margaret, Erin Doherty as Princess Anne and Gillian Anderson as prime minister Margaret Thatcher.

Meanwhile, Game of Thrones actor Jonathan Pryce will play Prince Philip and Elizabeth Debicki will play as Princess Diana for seasons 5 and 6.
