DNA Films is identified as the most appropriate film distribution company based on the research. DNA Films has produced several successful films within the same genre as the film being discussed, including 28 Days Later and 28 Weeks Later which involve zombies. They specialize in independent and British films, meeting the criteria of the film being a no-budget British production. Their experience distributing films within a similar genre would make them most likely to understand the concept and target the correct audience. Vertigo Films and Coffee Films were also considered but found less suitable due to differences in typical film genres or lack of experience with low-budget films.
