Donnie Wahlberg's thriller Saw II is the new Hallowe'en champion, after debuting at the top of the US box office with a haul of $30.5 million (GBP16.9 million).

The movie's earnings are almost double the $16.5 million (GBP9.1 million) second-place opening of Antonio Banderas and CATHERINE ZETA-JONES' sequel The Legend of Zorro.

It also easily outdid the 2004 horror hit Saw, which opened with $18.3 million (GBP10.1 million) over last year's (04) Hallowe'en weekend.

Prime, starring Uma Thurman and Meryl Streep, debuted at number three with $6.4 million (GBP3.55 million), followed by DREAMER: INSPIRED BY A TRUE STORY, with $6.3 million (GBP3.5 million).

Nicolas Cage's The Weather Man opened at number six with $4.3 million (GBP2.3 million), behind WALLACE + GROMIT: THE CURSE OF THE WERE-RABBIT, which earned $4.4 million (GBP2.4 million).
