I remember watching the movie as a child and still enjoy it today. Grandpa Joe is my favorite character. Charlie has four ailing grandparents. Always stubborn, traditional, and wary. But also supportive and caring. And the mysterious secret workers at Willy Wonka's chocolate factory. Grandpa Joe joins Charlie on the factory tour after Charlie finds the Golden Ticket. He saves the Commuter Capsule from the Vermicious Kids in the Great Glass Elevator with Charlie, Willy Wonka, and his family. 96 1/2 years old in "Charlie and the Chocolate Factory", Grandpa Joe is the eldest of Charlie's grandparents.
This is an example of a simile, a comparison between two things using the words "like" or "as." "Gloomy as the night" is the simile here, since his sadness is being compared to nighttime.
