In Harry Potter and the Prisoner of Azkaban, the packages of rechargeable batteries are clearly visible
Alfonso Cuarón directed Harry Potter and the Prisoner of Azkaban, the first and only film in the Harry Potter franchise. While we admire Cuarón’s unique vision, there was one detail that he and his team failed to notice.
The microphones worn by all of the performers in the film are visible in various moments, as are the battery packs that power them. Perhaps a boom should have been used instead. Perhaps the performers should have dressed in thicker, baggier attire.
