Because of the nature of the robot's design, Chris Hayward was unable to see out during the shoot and had to be led around by hand.
The original short Brian and Charles (2017) was shot for just £500 in the Welsh countryside. The cast and crew all rented an Airbnb for the duration of the shoot.
The film was originally set to start filming on the very first day that the UK went into lockdown for the first time in the Covid-19 pandemic. They had to wait six months before they could start making the film again.
Shot over a period of four weeks, mostly in and around Snowdonia National Park in Wales.
