 The wardrobe crew were shocked to discover, halfway through filming,  that only one dressing robe had been purchased for Arthur, and the  line had been discontinued by the manufacturer. The cast & crew were  then ordered to be particularly gentle with the robe for the  remainder of production. Towards the end of the series, it was  rumored that a second series would be made, and when shooting  wrapped the robe was locked away to preserve it in case it would be  needed again.
