Roald Dahl Wiki

Grandpa Joe is the tritagonist of the novel Charlie and the Chocolate Factory and its 1971 and 2005 film adaptations. He is Charlie's paternal grandfather (maternal in the 1971 and 2005 films) who accompanies his grandson to Willy Wonka's chocolate factory.

He is also stated in the book to be in his nineties and the oldest out of the grandparents; although both of the actors who played him were younger. And in the book he was described as bony, or resembling a skeleton.

Joe is often excitable, paranoid, stubborn and anxious that Charlie wins the contest. He takes his relationship with Charlie very seriously. Joe is also angry when Wonka dismisses Charlie without reward due to their theft of the Fizzy Lifting Drinks, and suggests to Charlie that he gives the gobstopper to Slugworth in revenge. He also says that he expects Charlie to find all five Golden Tickets and stubbornly expects Charlie to find one when he and Grandpa George give a Wonka bar to Charlie for his birthday.

he mentions to Charlie that he used to be an employee at Wonka's factory before Wonka had to close the factory and lay off all its employees. When Joe and Wonka meet again, Wonka questions if Joe had been one of the spies, and when Joe replies that he never was one, Wonka welcomes him back.
