Netflix fans do not miss a trick when it comes to their favourite TV dramas.
So it's no surprise that with tens of millions having already binge-watched Bridgerton, and with an enormous fan base for The Crown - people are finding similarities.
Fans of bother series are now calling out Netflix for using 'the same set' for both dramas.
In a video posted to TikTok, one fan took a closer look at various scenes to let others now why certain rooms the actors were in were so familiar.
One showed the Duke of Hastings and Daphne Bridgerton, played by Regé-Jean Page and Phoebe Dynevor, appear in front of the Queen at the Palace which appears to be the same room where Princess Diana, played by Emma Corrin, skates through a hall in The Crown.

Another also showed that the Duke of Hastings and Olivia Colman's Queen also share the same office.
Just don't tell her what the newlyweds got up to in there.
The fan captioned a TikTok video and wrote: "I guess they saved on the budget by sharing sets!"
The video proved so popular, watched more than 590,000 times, the account holder, known as rakhee_81, created a spin-off giving more examples.

Some even pointed out the similarities to another Netflix title, the film Enola Holmes, hit ITV series Downton Abbey and Sherlock.
One commented: "Netflix does this for so many shows! Once you notice you can't unsee it."
"They didn't even change out the photos," joked another
