Season four of <em>The Crown</em> will shine a spotlight on the relationship of Princess Diana and Prince Charles. Netflix has just uploaded a one-minute and 45 second trailer ahead of the show’s fourth season set to premiere on Sunday, November 15. “Here is the stuff of which fairy tales are made, a prince and princess on their wedding day. But fairy tales usually end at this point, with the simple phrase, ‘They lived happily ever after,'” the trailer’s narration says. “As husband and wife live out their vows, loving and cherishing one another – sharing life’s splendors and miseries, achievements and setbacks – they will be transformed in the process. Our faith sees the wedding day not as the place of arrival, but the place where the adventure really begins.” Season four is set during the late 1970s, as the Queen looks to safeguard the line of succession by ensuring a 30-year-old Prince Charles, played by Josh O’Connor, marries. The series will also touch on the Falklands War, and will explore growing tension between Queen Elizabeth II (Olivia Colman) and Prime Minister Margaret Thatcher (Gillian Anderson). Earlier in the month, the makers of the show revealed their replica of Princess Diana's famed gown that she wore to her wedding to Prince Charles in 1981. Corrin revealed to <em>Glass </em>magazine that the design was a replica. “One of the most iconic things was the wedding dress – that was an insane moment,” Corrin, 24, said of filming the fourth season. “The Emanuels, who designed her wedding dress, came in and gave [the wardrobe design team] all the original designs, so it was a complete replica." Corrin will only portray the princess in season four as the role will go to Australian actress Elizabeth Debicki for the final two seasons of the series. "It is my true privilege and honour to be joining this masterful series, which has had me absolutely hooked from episode one,” she said. Seasons five and six are expected to include the princess's death in 1997, which plunged the Royal Family into an annus horribilis. <em>Season four of The Crown will be on Netflix on Sunday, November 15</em>
