Brothers David and Keith Lynch have won The Big Pitch, a UK film production prize, with their film Different Shades Of Graham.

The brothers, along with producer Simon Thomas and director Brad Watson, joined four other finalists at the closing night of the Northern Lights Film Festival.

The finalists had been selected from 200 up-and-coming UK filmmakers and were given 15 minutes in which to sell their film.

UK industry body Skillset had provided training and development for the final teams as they competed for the production finance prize.

The panel, which included Eve Gabereau from Soda Pictures and Denise Parkinson from Bauer Media, gave its verdict but the public also helped to decide on the winners by voting online.

The brothers will be guaranteed production finance from Moxie Makers (which includes a post-production deal with Molinare), guaranteed UK distribution with Soda Pictures and international sales representation with Moviehouse Entertainment. The prize is valued at $368,000.

Their psychological thriller will receive its premiere as part of the Northern Lights Film Festival in 2009.

Keith Lynch said 'This is a life changing experience for us, we are so grateful to everyone for the fabulous support we have received. It has been a totally amazing journey and I can honestly say it has been an honour to work with all of the teams in the competition.'

The other finalists were:

Blackout, a dark neo-noir thriller directed by award-winning short film director Derek Boyes;

Til Jihad Do Us Part , a romantic comedy written by Shai Hussain that tells the story of Meena and her growing suspicions that her new fiance may be a terrorist; and

The Brightness , a satirical-comedy set in 2012 on the eve of the apocalypse, written and directed by Gary Reich.
