Rowling books that provide the basis for the films, so they know what's coming. Of course, young fans have already devoured the J.K. This 'Potter' earns its PG-13 rating - a first for the previously PG series about the boy wizard - as Harry grows into adolescence and learns more about his powers and his past.
If the third film in the Harry Potter series, last year's 'Prisoner of Azkaban,' seemed frightening with its soul-sucking Dementors and its German expressionist aesthetic, then the fourth installment, 'Harry Potter and the Goblet of Fire,' will have kids quaking in their seats - and perhaps wishing they had an invisibility cloak to hide beneath. Hermione Granger (Emma Watson), far left, Fred Weasley (James Phelps) and George Weasley (Oliver Phelps) examine the Goblet of Fire. Harry Potter (Daniel Radcliffe) finds himself selected as an underaged competitor in a dangerous multi-wizardary school competition. Ron Weasley (Rupert Grint), Hermione Granger (Emma Watson) and Harry Potter (Daniel Radcliffe) try to find out about the mysterious event that's supposed to take place at Hogwarts.
