The Legend of Zorro, which reunites Catherine Zeta Jones and Antonio Banderas, took $16.5m (£9.3m) after receiving lukewarm reviews.
Romantic comedy Prime, starring Meryl Streep, entered at number three.
Horse racing drama Dreamer, starring Kurt Russell and child star Dakota Fanning, slipped from number two to four, while Wallace and Gromit: The Curse of the Were-Rabbit fell to number five.

Nicolas Cage's latest movie Weather Man, directed by Gore Verbinski of Pirates of the Caribbean fame, was a new entry at number six, with takings of $4.2m (£2.3m).
The first Saw film was released over the Halloween weekend last year, taking $18.3m (£10.2m) in its opening three days.
But word-of-mouth boosted its popularity and it went on to be a DVD bestseller.
The original had a largely unknown cast but Donnie Wahlberg has joined the sequel as a police officer on the hunt for a serial killer.
Overall takings in the US and Canadian box office were down 6.5% on last year, although this decline was less than has been seen in previous weeks.
