Boy wizard Harry Potter has won millions of fans around the world thanks to JK Rowling’s spellbinding books, as well as the hugely successful big screen versions of the author’s bestselling novels.
They reprised their roles for six more films, alongside appearances from British acting icons, including Helena Bonham Carter, Robbie Coltrane, Ralph Fiennes, Jason Isaacs, Gary Oldman and Imelda Staunton.
But eagle-eyed fans have spotted many more famous faces in the movies over the years, including Bridgerton heartthrob Rege-Jean Page, children’s TV veteran Dani Harmer, and even Good Morning Britain host Ben Shephard has made an appearance in the hit saga.
Here, we take a look at some of the well-known stars you may not have noticed making their debut in Harry Potter films…
The 33-year-old actor shot to worldwide fame after starring as the charming Duke of Hastings in the hit Netflix drama Bridgerton last year, but Rege-Jean made his big-screen debut years earlier.
He had a small cameo in Harry Potter and the Deathly Hallows Part 1 back in 2010, appearing alongside Emma Watson’s character Hermione.
The British actor is one of the wedding guests as the nuptials of Ron’s older brother Bill Weasley, played by Domhnall Gleeson, and Fleur Delacour.

Rege-Jean Page’s Bridgerton co-star also had a starring role in the Harry Potter films, and Freddie managed to appear in not one, but three films in the wizarding saga.
The 34-year-old actor, who plays Prince Frederick of Prussia in the Netflix series, was cast as arrogant Quidditch player and Gryffindor student Cormac McLaggen.
He made his debut in Harry Potter and the Half Blood Prince, as well as both instalments of the Deathly Hallows films.

The diminutive actor, best known for his role as Mini Me in the Austin Powers movies, was cast as Griphook in the first film, Harry Potter and the Philosopher’s Stone.

The actress is best known for playing Tracy Beaker in the hit CBBC series The Story of Tracy Beaker, but before she made her debut in 2002 as the beloved outspoken character, she appeared in the first of the Harry Potter movies.
Dani played a Hogwarts student in Harry Potter and the Philosopher’s Stone, and her cameo was unearthed by an eagle-eyed fan.
“I think I found @DaniHarmer in Harry Potter and the Philosopher’s Stone, she is behind Oliver Wood after Hermione speaks,” they wrote, prompting the 32-year-old to confirm the news.
“Yep there I am,” she tweeted.
The Good Morning Britain host left viewers stunned as he revealed he had in fact played a wizard in Harry Potter and the Half Blood Prince, the sixth film in the franchise, back in 2009.
The 46-year-old had a small role in the hit film, described as ‘Diagon Alley Father’ in the credits, and he left his GMB co-host Susanna Reid in a state of shock after he unveiled his cameo during a segment on the morning show in 2019.
Andi Peters outed Ben’s big-screen debut as he introduced a competition from the Warner Brothers’ Studio Tour in London, and said: “You of all people should know where I am, Ben – you have dressed up and been here!
“Here is living proof of Ben in costume when he was here. Ben was in the movie Half Blood Prince – one of the Harry Potter movies – and that’s exactly where I am right now,” he said, as a picture of Ben in character flashed up on the screen.
Die-hard Little Mix fans managed to capture a grainy image of a fresh-faced little Jesy in Harry Potter and the Goblet of Fire, but it’s a blink-and-you’ll-miss-it cameo from the singer.
The 30-year-old, who also had a brief appearance in the 2002 comedy About a Boy, confirmed she was in the fourth Harry Potter film, which also starred Robert Pattinson.
Back in 2017, she was quizzed on her acting debut during an interview on an Australian radio show with her former Little Mix bandmates.
“Jesy you were in Harry Potter”, he asked, prompting Jesy to reply: “I was in Harry Potter!”
Julianne and Derek Hough
The famous siblings, best known for their appearances on Dancing With the Stars, the US version of Strictly Come Dancing, were also in two Harry Potter films.
Julianne, who also forged a successful acting career, was an unnamed Gryffindor student in Harry Potter and the Philosopher’s Stone, while Derek also starred in the same movie.
He can be seen wearing Ravenclaw robes as he holds an owl behind Emma Watson’s character Hermione while in the corridors of Hogwarts as students prepare to head home for Christmas.
The former Stone Roses frontman appeared in the first film, Harry Potter and the Philosopher’s Stone, as well as a brief cameo in the third film, Harry Potter and the Prisoner of Azkaban.
In the first film, he can be seen in the Leaky Cauldron pub, located in Diagon Alley, as Harry is intrigued to the wizarding world for the first time by Hagrid.
