The fair-haired Derek Hough was cast as a Ravenclaw, and can boast that he was also a stand-in for Tom Felton's character Draco Malfoy. The scene in which you can spot the choreographer is when the students are preparing to leave for the Christmas holiday. Hermione Granger, played by Emma Watson, walks through the Great Hall with her suitcase. For a split moment, the camera angles down the hallway, focusing directly on Hermione. Right behind her is Hough, holding his pet owl.

He gushed to Entertainment Weekly, "That's my big moment. I'm right in the camera's viewpoint, so every time you look at Hermione, you can see me, clear as day." Hough then went on to explain that he attempted to do a dramatic motion so that he was sure to get noticed, which looks like a bit of an excited leap in the released version of the "Harry Potter and the Sorcerer's Stone" movie.

That's the only appearance the future "Dancing with the Stars" dancer would make in the "Harry Potter" franchise. However, fans can spot Hough's sister, Julianne Hough, during a Quidditch match. He joked, "She had a crush on Daniel Radcliffe. She wrote him a love letter and sent him a teddy bear. They were like 12 years old." After the first film, the Hough siblings were too busy to sign up for being extras in future "Harry Potter" movies.
