Petch's short film 'Low Street' (2004) appeared in the Raindance, Foyle, LA and Soho Rushes Film Festivals where Petch was nominated Best Newcomer. A cast of two, the film stars Denis Lavant ('A Very Long Engagement', 'The Lovers on The Bridge') and Patrick Baladi ('Bodies', 'The Office'), and is shot across one location. The film was described as 'beautifully directed' by UK's Campaign Screen magazine. When 'Traitor' (2008) wanted to re-enact an SAS assault on a London townhouse they approached Petch. Using weapons and tactics as part of this tense and realistic thriller, Petch recreated believable action for the film, including a scene in which one of the cast had actually served with the SAS. Petch also comments on contemporary military issues appearing on Sky and BBC; TV and radio.
