Fans started lining up outside London's Leicester Square Saturday night for Sunday's premiere of "Harry Potter and the
Goblet of Fire."

Daniel "Harry Potter" Radcliffe thanked the rabid "Potter" fans and told the BBC: "If this doesn't get you exhilarated, nothing else will."

Similar sentiments came from Emma "Hermione" Watson, who called the atmosphere "amazing and completely overwhelming."

The fourth film in the "Potter" series is the darkest thus far and carries a 12-A rating in Britain, meaning no one under 12 will be admitted unless accompanied by an adult. It is rated PG-13 in the United States, which means parents are strongly cautioned that some material may be inappropriate for children under 13.

In addition to some violence, Harry gets his first girlfriend, the BBC said.

The movie is due to hit theaters Nov. 18.

Filming on the fifth movie, "Harry Potter and the Order of the Phoenix," is already under way with a 2007 release date planned.
