Benedict refers to portraits by Thomas Gainsborough and W.J.M. Turner's sky paintings. Turner was inspired to paint bright, colorful sunsets observed in England, and throughout the world, as the result of volcanic ash in the atmosphere following the eruption of Mt. Tambor in 1815. The eruption's debris caused average temperatures around the globe to decrease significantly, leading to the historic "Year Without a Summer" in 1816, and agricultural disaster and food shortages.
The episode won an Emmy Award for Outstanding Period and/or Character Hairstyling.
