Catering is obviously important for keeping everyone in the crew fed and energised. Still, production companies cannot just lay out food on several tables as there are also rules in place for catering.
First and foremost, the production company needs to come to an agreement with the film contact regarding the general catering arrangements and where the vehicles will be located. The caterers hired are also required to use a water bowser to hold dirty water in locations where doing so is possible. Caterers must also prioritise using environmentally friendly items for serving the crew.
Production companies are also urged to work with local businesses for their catering needs.
