Thanks Steve for the post....very informative.
I was also trying to work out the relationship between the realist style of OOOAiM and the avante garde British documentary movement. Such as Jennings' Spare Time, Listen to Britain and London can take it etc.
Was the GPO/Crown Film Unit a major influence on Studio made productions?
Humphrey Jennings is often credited with the first use of a documentary realist approach with "Fires Were Started". So stylistically, were P+P the first to use the documentary format in OoOAiM or do they not come into consideration because of the use of trained actors and a Studio made film?
Soz about the question being off thread topic
