“Harry Potter and “Game of Thrones” are completely different worlds.
But the worlds converge thanks to actors who have appeared in both.
While some of the crossovers may be recognizable, like Natalia Tena as both Tonks and Osha, others may come as a surprise.
Here are 12 actors that have appeared in both series
1. Catelyn Stark as Hermione’s mother
Michelle Fairley made a brief appearance in the first part of “Deathly Hallows” as Hermione’s mother. But “GOT” fans might know her best as the strong-willed Catelyn Stark.
2. Wildling Osha as Tonks
Natalia Tena has known throughout the “Harry Potter” fandom as the amazing Nymphadora Tonks, but don’t call her Nymphadora.
She joined “GOT” as the fearless wildling Osha in the first season until she and Rickon disappeared for a bit during season four and five. She briefly returned in season six, but she was killed by Ramsay Bolton when she tried to stab him. RIP, Osha.
3. Walder Frey as Argus Filch
David Bradley played Argus Filch, the often cruel caretaker at Hogwarts. He plays Walder Frey, the awful head of House Frey who betrayed the Stark family, in “GOT.”
4. Mance Rayder as Aberforth Dumbledore
Ciarán Hinds played Aberforth Dumbledore, Albus’ brother, in the final “Harry Potter” movie. Fans might recognize him as Mance Rayder, the King Beyond the Wall, in “GOT.”
5. Dickon Tarly as Cormac McLaggen
Freddie Stroma played the slightly obnoxious Cormac McLaggen, who annoyed Hermione during Professor Slughorn’s Christmas party. He showed up during the sixth season of “GOT” as Dickon Tarly, Sam’s younger brother.
6. Grand Maester Pycelle gave voice to Aragog, the giant spider
You won’t recognize Julian Glover in “Harry Potter,” because he was the voice of Aragog, the giant spider.
But you can recognize him as Grand Maester Pycelle in “GOT.”
7. Ian Whyte played various roles in GOT and gave whole body shots for Madame Olympe Maxime.
Standing at 7-foot-1, Ian Whyte has played his fair share of giant characters, including the whole body shots for Madame Olympe Maxime (also portrayed by Frances de la Tour).
He’s portrayed multiple characters on “GOT,” including a White Walker, the Mountain in season two, and Wun Wun the giant.
8. Spice King of Qarth as Bob
Nicholas Blane made an appearance in “Harry Potter and the Order of the Phoenix” as Bob, a wizard who worked with Arthur Weasley at the Ministry of Magic. Bob is the one holding the box.
In “GOT,” he played the Spice King, one of The Thirteen who rule Qarth. He was killed by fellow member and warlock Pyat Pree.
9. Bronson Webb played the role of a member of the Night’s Watch in GOT and played a role as Malfoy’s friend in Harry Potter
Bronson Webb played a Slytherin student and friend to Draco Malfoy in “Harry Potter and the Prisoner of Azkaban.” He’s the one on the right.
Webb played WIll, a member of the Night’s Watch who fled from the White Walkers only to be executed by Ned Stark for deserting his men.
10. Dagmer Cleftjaw as Amycus Carrow
Ralph Ineson plays Amycus Carrow, a Death Eater in three “Harry Potter” films. In “GOT,” he played Dagmer Cleftjaw, a raider for House Greyjoy. But after betraying Theon at Winterfell and stabbing Maester Luwin, Dagmer was in for a rude awakening when he and his men were flayed alive by the sadistic Ramsay Snow.
11. A Braavosi woman as Madame Irma Pince
Sally Mortemore played Madame Irma Pince, the librarian at Hogwarts, in “Harry Potter and the Chamber of Secrets.”
She popped into “GOT” as a Braavosi woman in the sixth season.
12. Archmaester Ebrose as Professor Horace Slughorn
Jim Broadbent has only just arrived in Westeros, making his first appearance in Season 7 premiere Dragonstone. He’s playing Archmaester Ebrose, who is mentoring Sam at the Citadel and specialises in healing.
In Harry Potter
He was Professor Horace Slughorn, a retired teacher who was coaxed out of retirement in The Half-Blood Prince to once more serve as Hogwarts’ Potions Master. He was, of course, the one who gave Tom Riddle his first real insight into the Horcruxes that would later help make Lord Voldemort so powerful.
