Heavy is the head that wears the crown — or so it seems in the Season 3 trailer of Netflix’s “The Crown” that dropped Monday.

Set 25 years after Queen Elizabeth’s coronation, we get a brand new cast of royals, headed by Olivia Colman, taking the scepter from Emmy winner Claire Foy. This time around, Helena Bonham Carter plays the queen’s saucy sister, Princess Margaret, shown reclining in a bubble bath and clearly up to no good.

Only she and the queen’s Corgis seem happy during what is, from all appearances, rough times for the monarchy. To a dirge-like rendition of “The Times They Are a-Changin’,” we see snippets of the 1960s and ’70s, a time of miners’ strikes and a sluggish economy.

“This country was still great when I came to the throne,” the queen is heard saying. “All that’s happened on my watch is that the place has fallen apart.”

Other new faces include Tobias Menzies as the Duke of Edinburgh, who suspects the monarchy may be on its way out, and Josh O’Connor as a love-struck (with Camilla Parker Bowles) Prince Charles.

Japan inadvertently got a sneak peek of the trailer on Sunday.

“The Crown” launches globally on Sunday, Nov. 17.
