The Fellowship of the Ring, the first of three Lord of the Rings films, has been given a PG certificate for UK cinemas.
It's the same classification as Harry Potter and the Philosopher's Stone, which is seen as the film's biggest rival.
Fantasy
The British Board of Film Classification saw the fantasy film - which stars Elijah Wood - last week and says it's fine for 12-year-olds.
But they don't think it's right for those under 8-years-old as it has scenes of "battle violence and fantasy horror", so they didn't give it a "U".
More popular than Harry?
The Fellowship of the Ring, directed by Peter Jackson, was filmed in New Zealand and it's expected to be more popular there than Harry Potter.
It's predicted to make NZ$13 million (about £4m) compared to the NZ$6.5 (£1.9m) Harry Potter's expected to make when it opens there on 29 November.
The Fellowship Of The Ring has its world premiere in London on 10 December, opening nationwide on 19 December.r.
