Robin Williams is one of the most gifted comedic talents to ever grace the silver screen. He was able to bring happiness and joy to all of his viewers, and he was never short on a variety of impressions and a natural wit. Of course, life is not always perfect, and Robin Williams grew up as an only child whose parents were constantly working, and he was constantly moving from place to place.

Robin was able to identify with Alan Parrish in this regard, and in an interview with The Christian Science Monitor, Mr. Williams also gave his summation of the purpose of the film itself: “It’s the fear that all children have of abandonment and separation from their parents. That’s where my character comes in. I play a boy who has been swallowed up into the game. By the time he is able to come out, 26 years later, his parents are dead, and he feels lost and alone.”

Author Van Allsburg was the creator of the original 1981 Jumanji picture book, and it turns out he created the novel out of pure resentment towards the popular board game Monopoly. Apparently Mr. Allsburg wasn’t too fond of spending eight days locked in a room wasting away at a game that in the end teaches you that money is power. He also wasn’t too fond of the idea of a game that had no real stakes, but that players would invest entire days at a time into.

In an interview with Scholastic, he elaborated on his mental processes when crafting the novel. “When I was a little boy and I would play games like Monopoly, they seemed kind of exciting, but when I was done with the game, all I had was fake money. So I thought it would be fun and exciting if there were such a thing as a game board where wherever you landed on a square and it said something was going to happen, then it would really happen.”
