No, this isn’t some form of wizardry.
Derek Hough and Julianne Hough really did appear in Harry Potter and the Sorcerer’s Stone when they were kids.
This revelation was made for many fans after the Dancing With the Stars judge posted a video of the siblings’ cameos in the 2001 movie to Instagram.
“Did you know @juleshough and I were in the first Harry Potter film?” Derek wrote alongside the footage Dec. 4. “We spent three months in the Great Hall, the Forbidden Forest, and even the Quidditch pitch! It was incredible to be part of such a historic moment. And I may have ‘accidentally’ taken a Ravenclaw robe, scarf, tie, and a few pieces of silverware from set… but shh, don’t tell!”
In fact, the six-time mirrorball champion noted he even “stood in for Draco Malfoy to set up shots”—though the character was played by Tom Felton.
Still, it’s not like Derek and Julianne have kept their Potter past in the chambers of secrets. On the contrary, they’ve spoken about their experiences, including how they got the gig.
“We lived in London as kids, from 10 to 15 for myself, and we went to a performing arts school,” Julianne told Access Hollywood last December. “And they needed a lot of kids, so they got all the stage school kids to come. We were just extras. But we were the only Americans, so they were like, ‘Stop talking in the background.'”
