A lot has been achieved by director Danny Boyle in the 20 years since his first full-length film was released – not least his universally acclaimed opening ceremony for the London 2012 Olympics.

But Shallow Grave did not initially meet with such acclaim. However, screenings such as this one prove that there are an increasing number of devotees to the dark, corrupted tale of a flat-share gone wrong willing to commemorate its longevity.

To celebrate the anniversary, lead actress Kerry Fox and composer Simon Boswell came to the Duke Of York’s to answer questions after the screening, and both recalled their roles in the film fondly.

Boyle biographer Amy Raphael posed the questions, marvelling at how the film had anti-Thatcher undertones, just how tight the budget was, and exactly how the gripping and climactic stabbing was achieved. While Fox’s remembrances were a trifle hazy, there was no doubting the affection in her voice.

The understandable absence of Boyle himself left certain questions unanswered. But for such a cynical and cold tale of double-crossing to be remembered by its producers and fans alike for so long spoke volumes about how engrained it now is in the nation’s psyche.
