Props

The only props that I used in filming were the telephone and the mobile phone, both important props for the entire conversation and relation between the driver and the call receiver for the breakdown services.
The prop used for the call centre of breakdown services:
A typical telephone of the 20th century was what I was aiming for, rather than a headset, because I wanted something that my actor could pick up that was really substantial so that it was made clear that it was him answering the phone call and something more familiar. Not having a headset also meant that the actor's (David) emotions could been seen more easily in close-ups.
I used the mobile phone for the driver, because of it's typical practicality in the fact that most drivers would have a phone that was portable and easy to bring in a car.
