When it comes to “Harry Potter,” everybody knows the film’s leading trifecta: Daniel Radcliffe, Rupert Grint, and Emma Watson.
But what about the dozens of other witches, wizards, and muggles who graced the screen throughout the series? While you were watching Harry and his friends fight dragons and hunt horcruxes, these performances from veteran actors and youngsters just beginning their careers might have totally passed you by.
From cameo appearances from the cast of “Dancing with the Stars” to a member of the band Radiohead, here are 16 actors you might have missed in “Harry Potter”:
Alfred Enoch has come a long way since his days playing Dean Thomas in 'Harry Potter.' Today, you can spot him as law student Wes Gibbins on 'How to Get Away with Murder.'
Scarlett Byrne kept company with fellow Slytherin Draco Malfoy as the sour Pansy Parkinson. Since then, she's starred in a different magical world as Nora Hildegard on 'The Vampire Diaries,' and can now be seen playing Lacey on 'Mary + Jane.'
Verne Troyer was the first of two actors to play Griphook the goblin in 'Harry Potter,' but you probably recognise him from his most famous role as Mini-Me in 'Austin Powers.'
John Cleese haunted the Hogwarts halls as Nearly Headless Nick. Cleese is better known for his sketch-comedy work in 'Monty Python.'
In 'Harry Potter,' Luke Youngblood palled around with Harry and their fellow Gryffindors. 'Community' fans will recognise Youngblood from his role as Magnitude.
Frank Dillane played a menacing Tom Riddle, the boy who would become the evil Lord Voldemort. Now, he's probably best know for his role as Nick Clark on 'Fear the Walking Dead.'
Julianne Hough had a cameo appearance as an unnamed Gryffindor in 'Harry Potter and the Sorcerer's Stone.' She went on to a successful TV career on 'Dancing with the Stars' and scored the role of Sandy in 'Grease Live!' last year.
Derek Hough also had a cameo, playing a Ravenclaw student holding an owl and heading home for Christmas in 'Harry Potter and the Sorcerer's Stone.' Like his sister, Hough went on to compete on 'Dancing with the Stars' and more recently starred in 'Hairspray Live!' as Corny Collins.
You might remember Domhnall Gleeson, and his flaming red hair, as Ron Weasley's oldest brother, Bill. More recently, Gleeson starred in 'Ex Machina' and played General Hux in 'Star Wars: The Force Awakens.'
Freddie Stroma drove his Hogwarts classmates nuts as the pompous Cormac McLaggen. In 2012, Stroma showed off his singing chops as Luke in 'Pitch Perfect,' and currently plays the similarly pompous character Adam Cromwell on 'UnREAL.'
Michelle Fairley had a small appearance as Hermione Granger's mother in 'Harry Potter and the Deathly Hallows.' But, now you'll probably recognise her most from her role as loyal matriarch Catelyn Stark on 'Game of Thrones.'
Natalia Tena fell in love with a werewolf playing the auror Nymphadora Tonks. These days, she can also be recognised for her role on 'Game of Thrones,' as Osha.
Warwick Davis actually had two different roles in 'Harry Potter,' Griphook the goblin and Professor Flitwick. In 2016, he played the interstellar scout Wollivan in 'Star Wars: The Force Awakens' and continues to work within the 'Star Wars' realm, voicing the character of Rukh in the 'Star Wars: Rebels' series.
Johnny Greenwood was the lead guitarist of Weird Sisters, the band that rocked out on stage at the Yule Ball in 'Harry Potter and the Goblet of Fire.' In real life, Greenwood is a member of the band Radiohead.
David Tennant snarled as Barty Crouch Jr. in 'Harry Potter.' Outside of the wizarding world, he's made a name for himself on shows like 'Doctor Who' and Netflix's 'Jessica Jones.'
