Glen Leyburn and Lisa Barros D'Sa start shooting their joint feature debut, Cherrybomb, today in Belfast.
The coming-of-age drama stars Rupert Grint, Kimberley Nixon and Robert Sheehan. Producers are Generator Entertainment, Green Park Films and Octagon Films.
The story is about two teenage boys whose friendship is tested when a troubled beauty comes to town and puts them in danger.
Daragh Carville (Middletown) wrote the screenplay. Belfast-based Leyburn is known a a designer and music video director and Barros D'Sa as a writer and development executive. They worked together on the 2006 short The 18th Electricity Plan.
Cherrybomb marks the second film from Mark Huffam and Simon Bosanquet's Generator Entertainment. They have partnered with Belfast-based Michael Casey's Green Park Films, who developed the project with Brian Kirk, and James Flynn's Dublin-based Octagon Films.
Famed musician David Holmes has come on board for the score.
'We are delighted to be working with Michael Casey of Green Park on this innovative and exciting film,' said Bosanquet from Generator.
Mark Huffam added: 'Daragh Carville's Belfast-set script gives a cool, contemporary twist to the traditional buddy-movie, set squarely against the backdrop of a city in the process of rebuilding its identity - it's perfect material for Glen and Lisa's fresh and original talents.'
Financiers for Cherrybomb include the Irish Film Board, Northern Ireland Screen, BBC Northern Ireland and the Broadcasting Commission of Ireland. International sales are being handled by Robbie Little's The Little Film Company.
Generator's first feature, Paddy Breathnach's Freakdog, will have its premiere at Film4 Frightfest in London on Aug 22; the company's third film will be Chris Hartwill's supernatural thriller Ghost Machine.
