The expensive time to discover your film hasn’t got a clear idea is when the crew is already standing in a room with the lights on. Pre-production is the chance to answer the awkward questions while the answers can still change the plan.

A shared plan gives everyone something to work from before the camera comes out.

It starts with the brief. Decide who the film is for and what you want it to achieve. Those decisions affect everything from the tone of an interview to the shots you need, and they give you a way to judge whether an idea belongs in the film.

Give the film a shape

Even an interview-led or documentary-style piece needs some structure. You may not know the exact answers yet, but you can work out what subjects need covering, how the story might develop and what footage will help the viewer follow it.

A script, storyboard or shot list turns that thinking into something the crew can use. It also gives the editor a fighting chance. If the film needs to move from one part of the story to another, plan the material that will make that transition possible.

The list should guide the day without making every decision rigid. Once the essential coverage is clear, there’s room to notice a better angle or follow a useful answer. It’s easier to be flexible when you know what you still need to come home with.

Work through the unglamorous bits

Locations and camera kit tend to get attention. Access arrangements and somewhere to park deserve a turn too. A few practical confirmations can save a surprising amount of standing around.

• Check location permissions, access times, parking and power before building the schedule around a space.

• Confirm the crew and kit the brief needs, with clear responsibilities and call times.

• Plan around cast or interviewee availability, leaving time for setup and changes between shots.

• Have a weather alternative where needed, and include breaks and lunch. People remain people even when there’s a shot list.

Share the plan with the people doing the work. The director, producer, camera crew, sound team and editor need to understand the project and how their part fits. Leaving the editor out of that conversation can be particularly unhelpful when the proposed shoot creates a problem for the proposed edit.

Make the plan fit the budget

Pre-production is also where ambition meets the available money. Work out which parts of the film matter most, what can be simplified and where extra time or specialist support will make a useful difference.

Those choices are much easier to discuss before anyone has been booked. They help a client understand what the quote covers and give the production a realistic basis for working out the schedule.

Spend the planning time on decisions people can use. A clear brief and an achievable day are far more helpful than a large document nobody has read. And if the whole plan still depends on fixing something in the edit, have that conversation with the editor now.
