This National Film Unit documentary provides a fascinating behind-the-scenes look at the various stages of 40s film production at the relatively nascent unit, from shoot to post production. It was made to be screened continuously (thus the ‘loop’ title) at exhibition theatrettes. There’s genial interaction among the cast and crew (see backgrounder for who they are). Directed by pioneer woman director Kathleen O’Brien, the filming took place at the unit’s Darlington Road studios in Wellington, close to where Weta Workshop and Park Road Post now operate in Miramar.
