As servants drag the unconscious Burns from someone's house after the game of charades, a white Arnold Clark rental van is clearly seen extreme screen left.
As Burns lies ill in bed towards the end of the film, an exterior shot of the house clearly shows a Scottish Tourist Board sticker in the window and modern commemorative plaques on the wall. Through the open door, a bright red fire alarm can be seen and the building next door has a modern Velux roof window.
