Paramount's high testosterone military drama Rules Of Engagement (pictured) topped the US box office for the second week in a row over the weekend with a $10.9m take on 3,190 screens, bringing its 10-day total to $30.6m. The film, sold in foreign territories by Seven Arts International, echoes the success of other solid Paramount thrillers from last year, The General's Daughter and Double Jeopardy, although it looks unlikely that it will top $100m as those films did.

Meanwhile, Columbia's female-skewed 28 Days opened second with a $10.4m gross. Playing on 667 fewer screens than Rules, it scored a higher per screen average of $4,122 - the highest in the top ten. The film stars Sandra Bullock as a New York bohemian party girl sent to rehab for 28 days and depicts her gradual realisation that she is an addict. Reviews were generally upbeat for the picture which co-stars Viggo Mortensen, Dominic West, Diane Ladd, Steve Buscemi and Elizabeth Perkins and was directed by Betty Thomas.

Spyglass Entertainment's Keeping The Faith, the first in-house production from the Disney-based independent, grossed a respectable $8.2m in its opening weekend on 2,152 screens. Starring Edward Norton, Jenna Elfman and Ben Stiller and directed by Norton, it tells the story of two best friends, one a rabbi and one a priest, who fall for the same girl. Spyglass handles foreign distribution, with BVI taking many regions.

Lions Gate Films finally opened its film adaptation of American Psycho on 1,236 screens over the weekend, grossing $4.9m for a screen average of $3,964. The darkly comic film directed by Mary Harron has been plagued by controversy in the same way as its source novel by Bret Easton Ellis, but reviews following its world premiere at the Sundance Film Festival in January have been good and the film's delicate touch and minimal on-screen blood and guts helped limit the controversy. The movie stars Christian Bale, Willem Dafoe, Chloe Sevigny, Samantha Mathis and Jared Leto.

The only other wide opener was Marek Kanievska's Where The Money Is from USA Films which took a disappointing $2.7m on 1,538 screens. Sold internationally by Intermedia, the film received a mixed bag of reviews largely praising stars Paul Newman and Linda Fiorentino but slamming the plotting and story.

Miramax Films opened British smash East Is East on four screens and scored approximately $52,000 for a screen average of $13,000. It is set to go to about 30 screens next weekend.
