Alfonso Cuaron’s shrunken zombie heads seen in Prisoner of Azkaban appear poised to make a comeback in the Wizarding World of Harry Potter’s Diagon Alley expansion.

A new casting call posted by Universal Orlando reveals that they are looking for people to use their “Caribbean accent” for an unspecified role.

Concept art for Diagon Alley shows that the Knight Bus will be placed on the London waterfront. Since the shrunken heads were inside the bus, one could assume that they will be speaking to people who enter or pass by the bus.

The casting call reads, “Universal Orlando® is seeking Male and Female Actors to bring Harry Potter’s world to life for our guests as they continue the journey from Hogsmead™ to Diagon Alley™. Use your best British dialect as you interact with guests exploring two amazing theme park experiences that combine into one complete magical journey! Please prepare a one-minute monologue in a British or Caribbean accent. Select candidates may be requested to attend a required callback on Tuesday, January 28th.”

The shrunken heads were one of Cuaron’s personal touches for his Harry Potter movie. In an interview on the film’s DVD, author J.K. Rowling said, “I wish I’d thought of that,” when speaking about the heads.

Universal Orlando will be holding a webcast on January 23 to unveil new details about The Wizarding World of Harry Potter: Diagon Alley. The park is expected to open this summer.

The theme park looks to be pulling from all aspects of the Harry Potter world for this highly-anticipated expansion. A permit filing in December revealed that an object from The Tales of Beedle the Bard will also be making an appearance.
