Halloween-minded moviegoers flocked to Saw II over the weekend. The horror sequel topped the box office with $30.5 million, nearly twice the $16.5 million debut of No. 2, The Legend of Zorro. Rounding out the Top 5 was the new Uma Thurman-Meryl Streep knee-slapper Prime (No. 3 with $6.4 million), Dreamer (No. 4 with $6.3 million) and Wallace & Gromit (No. 5 with $4.4 million). Finally, the forecast looks bleak for Nicolas Cage's The Weather Man. The character-driven comedy opened at No. 6 with a dreary $4.3 million. In related news, weather puns are fun!
