As the guests are sitting in silence around the main piano tent Mrs. Rogers (Moira Lister) suddenly states "See. That's just the beginning. They keep it up all night." She is referring to the annoying roaring of lions in the evenings but the sound effect of a lion roaring is missing from the scene.

When the survivors are burying the first victim, one woman comments that they "didn't even know" his first name. During the accusation scene, all ten characters are present and all ten characters' full names are used, but perhaps she forgot due to stress (or the copious amount of alcohol she consumed), or she wasn't paying attention during the recording.
