One of the most successful series of fantasy novels of all time, Harry Potter! Written by the British author J.K Rowling, the novel series later turned into one of the most successful film series too. The movies show the life of a young wizard named Harry Potter and his friends Hermione Granger and Ron Weasly. They are students at Hogwarts School of Witchcraft and Wizardry. But since everybody saw the series or read the series, I am going to save some time on writing about it. Below we have posted a video that shows the cast of Harry Potter ”then and now.” Check out the video below and enjoy.
