Emily Longeretta Warning: This story contains spoilers from “Queen Charlotte: A Bridgerton Story,” now streaming on Netflix. “Queen Charlotte” may be an extension of the “Bridgerton” universe, but its brand-new story by Shonda Rhimes is quite different, with a much more serious tone. “The series in itself is like a different beast,” says Corey Mylchreest, who portrays young King George III in the Netflix drama. “It feels like ‘Bridgerton’ but it has maybe darker moments to it, and it’s a little bit grittier. So it feels like its own thing.” The story of Queen Charlotte and King George III was briefly touched on in Season 2 of “Bridgerton,” but this prequel dives in to the origin story of a young Charlotte (India Amarteifio) as she embarks on her arranged marriage to a young King George. Charlotte’s fearlessness — especially as a Black woman marrying the King of England — changes the country, under the auspices of what the show calls “The Great Experiment.”
