StudioCanal records its biggest-ever UK haul as Tinker Tailor overtakes Unknown’s £6.5m ($10.1m).

StudioCanal’s thriller Tinker Tailor Soldier Spy remained one step ahead of its rivals at the head of the UK box office, grossing £2.1m ($3.3m) - a drop of only 25% - in its second week for £6.9m ($10.7m), to become the UK distributor’s biggest grosser ahead of thriller Unknown (£6.5m/$10.1m).

Tinker Tailor increased its number of screens by 10% to 422 and grossed a week-high screen average of £4,988 ($7,720).

Only £480,000 ($746,591) separated second from tenth over a congested and unspectacular weekend. Warner Bros’ second-placed Crazy, Stupid, Love was the highest of six top 15 newcomers, making a modest £860,112 ($1.3m) from 396 screens at an average of £2,172 ($3,362). However, somewhat surprisingly Glenn Ficarra’s comedy-drama opened £200,000 ($311,084) down on the director’s previous directorial effort I Love You Phillip Morris.

Lionsgate’s action-drama Warrior entered the UK chart in third on £808,410 ($1.25m) from 383 screens at an average of £2,111 ($3,267), becoming the distributor’s second-best opening of the year behind The Mechanic.

In its sixth week the still-impressive The Inbetweeners Movie grossed a further £754,226 ($1.2m) from 406 screens for a cumulative of £43.3m ($67.0m), making the surprise smash comedy the fourth biggest film of the last 12 months in the UK.

Icon’s critically acclaimed Drive, the second Ryan Gosling title in the top five, debuted in fifth position, grossing £607,454 ($940,186) from only 176 screens for the third-best screen average of the week, £3,451 ($5,342).

Entertainment’s Killer Elite posted an uninspiring opening in seventh on £481,143 ($744,688) across 293 locations, failing to capitalise on a cast including Jason Statham, Robert De Niro and Clive Owen. The total was almost half the debut haul of Statham’s The Mechanic and was De Niro’s smallest UK opening since Machete flopped in November 2010.

Universal’s rerelease of Jurassic Park took £245,422 ($379,851) from 276 at a lowly average of £889 ($1,376)  and Eros’ Mausam, after a one week delay, debuted on a healthy £188,488 ($291,732) on only 42 screens for a predictably high screen average of £4,488 ($6,946).

In a busy week for releases, this frame sees saturation coverage for Lionsgate’s Abduction, Universal’s The Debt, Entertainment’s Shark Night 3D and Fox’s What’s Your Number? There are wide releases for Artificial Eye’s Melancholia and eOne’s Red State.
