Two fandoms are coming together.
While watching the hit new period drama Bridgerton, fans of the Harry Potter franchise started to notice one actor looked very familiar.
After less than a month after the show hit Netflix, viewers have connected the dots — actor Freddie Stroma, who plays Prince Friedrich of Prussia, was also Cormac McLaggen in the final Harry Potter movies.
Stroma, 34, fought for Hermione Granger's (Emma Watson) affections in Harry Potter and the Half Blood Prince, and played Quidditch against Ron Weasley (Rupert Grint), who despised him.
He also appeared in Harry Potter and the Deathly Hallows: Part 1 and Part 2.
He wasn't a very liked character, with the actor revealing to MTV News in 2016 that Cormac was "arrogant".
"At the end of the day, he's a Gryffindor, but he's probably the worst side of Gryffindor that you can have. He's a bit arrogant about the talent he has. I don't think he's really misunderstood. I think he's very confident and really egotistical."
However, he is quite liked as Prince Friedrich.
"HOLY S*** THAT PRINCE DUDE FROM BRIDGERTON WAS IN HARRY POTTER HOW DID NEITHER ME OR MY MOM PICK THAT OUT," one fan tweeted.
Another added, "Not me just now realising that the guy that played the prince on Bridgerton also played Cormac McLaggen on Harry Potter."
The show is based on the popular novels by Julia Quinn, which follows the elite Bridgerton family through Regency England as Daphne Bridgerton finds love.
The series is a long-awaited project from Shonda Rhimes, and is part of an eight-show deal she made with Netflix in 2017.
This week, Netflix faced the huge problem that the show's sex scenes had made their way to porn sites.
The streaming service is doing whatever it can do try remove the scenes that feature lead actors Phoebe Dynevor and Regé-Jean Page.
Dynevor, who plays the socialite Daphne Bridgerton, is reportedly devastated over the news.
An insider revealed to the Sun: "Bridgerton's sex scenes appearing alongside some of the most obscene material the web has to offer has sparked horror and anger.
"Raunchy set pieces have contributed to the buzz but it is a prestige drama based on best-selling novels.
"To peddle scenes as pure smut is beyond the pale.
"It's been particularly distressing for Phoebe and Regé-Jean, two young actors who signed on for the role of a lifetime and did not consent to being exploited in this way.
"Netflix have been working tirelessly to hunt down pirates and eliminate misuse of their intellectual property. Anyone thinking about trying this will have the full force of the globe's biggest streaming service against them."
The series has had more than 70 million households watching.
