He later revealed himself as one of the Istari, and eventually became known as the wisest of and most powerful of that order. Gandalf was more knowledgeable than Saruman about many matters regarding Sauron and the Rings of Power, and was head of the White Council before the War of the Ring, he later grew jealous and afraid of Gandalf,which was the reason of his betrayal.

Dumbledore is the headmaster of the wizarding school, Hogwarts. He is also the founder and leader of the Order of the Phoenix, an organisation dedicated to fighting Lord Voldemort. Dumbledore is a very wise man who knows that Harry (the main character) is going to have to learn a few hard lessons to prepare him for what may be coming in his life. He allows Harry to get into what he wouldn’t allow another student to do, and he also unwillingly permits Harry to confront things he’d rather protect him from. He also acts as a father figure in the parent-less Harry’s life.

Alfred Pennyworth supported Bruce’s decision to become Batman and has helped him on a few occasions. He also continues to give Bruce guidance even when he is Batman. When the Joker began to terrorize Gotham, it was Alfred who helped Bruce conclude who he was and helped him identify the deadly toxins in the Jokers household products. When the lovely Vicki Vale came into Bruce’s life, he was confused about telling her that he was Batman. Through Alfred’s wise words he convinced him to do so, although it was Alfred who eventually told her.
How are these wise old men similar?
In each film, the wise old men play major and minor roles in the hero’s life. However, the role of the wise old men in the films are very similar because they are all old, provide the hero with guidance and wisdom, and act as a father figure in the hero’s (main character) life. How major or minor the wise old man role is depends on the hero’s journey.
