Harry Potter and the Sorcerer’s Stone is the first film in the Harry Potter series based on the novels by J.K. Rowling. It is the tale of Harry Potter, an ordinary 11-year-old boy serving as a sort of slave for his aunt and uncle who learns that he is actually a wizard and has been invited to attend the Hogwarts School for Witchcraft and Wizardry. This Conductors Cap is clearly seen at the beginning of the film on Platform 9 when Harry asks the Platform Conductor where Platform 9 3/4 is.
