The opening three day gross of Kevin And Perry Go Large has given Icon Film Distribution its first box office hit and number one film in the UK. The comedy teenage duo took $3.2m (£2m) over the Easter weekend (April 21-23). Playing on 336 screens, the British adaptation of a TV comedy sketch, which stars Harry Enfield and Kathy Burke, scored a substantial site average of $9,536 (excluding previews of $600,000). The distributor's first release - and previously most successful - was Drop Dead Gorgeous, which opened in September last year grossing a total of $2.3m.

Despite the school holiday weekend, Pokemon: The First Movie dropped 43% to number two with a weekend gross of $2m, while Erin Brockovich at number three is well on the way to hitting $15m.

The other successful new entry was American Psycho, which scooped $1.2m from 172 sites to take the number five slot. A huge $172,725 of that sum came from just eight screens in London's West End.

Not so noteworthy were the releases of romantic drama The Story Of Us and family comedy Snow Day, which opened with three-day site averages of $1,626 and $512 respectively.
