Fans of Harry Potter who are also fans of Game of Thrones are always excited when they see some of their favorite actors pop up.
While some actors who appeared are a little obvious, some were very easy to miss!
Michelle Fairley made a brief appearance in ‘Harry Potter’.

Michelle Fairley briefly appeared in Harry Potter and the Deathly Hallows as Hermione’s mother.
In Game of Thrones , she played Catelyn Stark, who met a tragic fate (like most Starks did).
Bronson Webb basically played a Slytherin both times.

Bronson Webb was a friend to Draco Malfoy in Harry Potter and the Prisoner of Azkaban .
You might remember him as Will in Game of Thrones , who fled the Night’s Watch to escape the White Walkers.
Jim Broadbent went from a professor to the Citadel.

Professor Slughorn isn’t exactly a fan favorite but he wasn’t unloved either. He’s just a little daft.
In Game of Thrones he appeared at the Citadel as Archmaester Ebrose.
You definitely wouldn’t have recognized Julian Glover.

In Harry Potter he played the voice of Aragog, Hagrid’s giant spider friend.
He had an actual human role in Game of Thrones as Grand Maester Pycelle.
Freddie Stroma went from obnoxious to sweet.

Freddie Stroma played Cormac McLaggen in Harry Potter who was basically obsessed with Hermione Granger. Actually, he was more obsessed with himself.
In Game of Thrones he was one of the two actors who played the fiercely loyal Dickon Tarly.
Natalia Tena didn’t last long in either.

In Harry Potter Natalia Tena plays Tonks, our favorite Auror.
She plays an equally fearless character in Game of Thrones , Osha. She met an untimely fate when Ramsay Bolton killed her.
Ian Whyte plays some not so gentle giants.

If you didn’t recognize him, don’t be too hard on yourself. In Harry Potter Ian Whyte played Madame Olympe Maxime for the full body shots.
In Game of Thrones he actually played more than one character. He was The Mountain in season two and has played giants.
Nicholas Blane became a king.

Nicholas Blane had a brief appearance in Harry Potter and the Order of the Phoenix as Bob. He was a wizard at the Ministry of Magic.
He upgraded his character in Game of Thrones to the Spice King, who was one of The Thirteen who ruled Qarth.
Ciarán Hinds plays major characters in both series.

While Ciarán Hinds’ time was short in Harry Potter , he still gave a memorable performance as Aberforth Dumbledore.
In Game of Thrones he is almost unrecognizable as the King Beyond the Wall, Mance Rayder.
David Bradley has a knack for playing characters fans hate.

In Harry Potter he played Argus Filch, who was never a fan favorite.
His character on Game of Thrones , Walder Frey, is the one who betrayed the Stark family. He thankfully got what he deserved when Arya got revenge.
