The Farrelly brothers latest comedy Me Myself And Irene opened in the UK over the weekend with $1.9m (£1.3m) from 357 screens, including previews of $126,743 (£86,946). Distributed by 20th Century Fox, the comedy starring Jim Carrey and real-life wife Renee Zellweger, won the number one spot and a screen average of $5,278 (£3,620). However this is considerably lower than the opening of There's Something About Mary two years ago of $3m (£2.1m) from 315 screens, including previews of $197,612 (£135,562).

Scary Movie dropped 30% on its third weekend to take a three-day gross of $1.5m (£1m) at second place in the chart. Its 17-day total has now reached $10.5 (£7.2m). The British heist movie Snatch has passed $15m (£10m) after 24 days and is on course to at least equal Lock, Stock And Two Smoking Barrels' $17.2m (£11.8m).

The other major weekend opener was Space Cowboys from Warner Bros which grossed a mediocre $827,821 (£567,885), including previews of $86,719 (£59,489), from 235 screens.

Two limited releases failed to make any box office impact: Play It To The Bone, the first release from Filmgroup's Redbus Film Distributors since Maybe Baby's June 2 opening; and Elephant Juice, the delayed first feature film from Amy Jenkins, creator of TV series This Life.

Play It To The Bone, starring Woody Harrelson and Antonio Banderas, grossed just $16,378 (£11,235) from 74 screens - a tragic screen average of $221. Elephant Juice, produced by the now-defunct Miramax-backed HAL Films, did a little better, but still only picked up $14,708 (£9,359) from 39 screens - a screen average of $377.
