Gwizdo is changed from how he was in the series. In the TV show, he is charismatic and fairly attractive. In the film, he's grimy and unpleasant.

In one scene Gwizdo asks what the tree illustrated on the calendar is for, and Lord Arnold answers that it's for scale to compare to the size of the World Gobbler. This is a call-forward to the episode "Gland of the Mimikar", where Gwizdo finds a picture of a tree in an illustration of the Mimikar for scale.

The film is a prequel to the TV series, taking place roughly ten years before the first episode.

The film was released between the first and second seasons of the series.

In the German dub, Sven Plate reprises his role as Gwizdo.
