Trivia

When Eric is first setting up his total station instrument in the forest the electronic bubble won't level, so he takes out a plumb bob and hangs it from the bottom over a stake; this method is not to level the instrument but to centre it over a point, however if the instrument is being moved they would have the same effects shown.

Brendan Conroy and Donncha Crowley both appeared in The Green Knight.

This is a rare appearance from around this time what Niamh Algar had no visible tattoos in a role but the birthmark she has on her right hand is clearly visible.
