The film is the first of the series to receive a PG-13 certificate in the US, and a 12A in the UK. Filming began in early 2004. The Hogwarts scenes were shot at the Leavesden Film Studios. Five days after its release, the film had grossed over US$102 million at the North American box office, which is the third-highest first-weekend tally for a "Harry Potter" film behind "Harry Potter and the Deathly Hallows – Part 1" and "Part 2". "Goblet of Fire" enjoyed an immensely successful run at the box office, earning $896 million worldwide, which made it the highest-grossing film of 2005 and the sixth-highest-grossing film in the "Harry Potter" series.
