Kids and adults assembled in Festival Square to try their hand at graffiti, before a team of award-winning breakdancers completed the event with a spectacular array of stunts.

The huge wall was modestly decorated to begin with. The two main characters from the Sundance smash hit The Wackness lay against an outline of the New York cityscape rendered by a local street-art expert.

Within moments the wall was transformed into a profusion of colour, enhanced only by the gravity-defying moves of the dancers.

In due spirit, a ghetto-blaster filled the Square with 90s hip-hop classics as featured in the film.

The Wackness is an exuberant comedy set in the nineties. A drug-addled psychiatrist played by Sir Ben Kingsley forms an unlikely bond with his dope-peddling patient, a streetwise teenager with a taste for the doc’s daughter.

The film’s UK Premiere took place yesterday evening. A second screening takes place tonight, Saturday 21 June at 21:45 at Cineworld.
