Albus Dumbledore in “Harry Potter”
In the first two films of the “Harry Potter” franchise, Headmaster of Hogwarts Albus Dumbledore was played by Richard Harris, who was expected to play the character throughout the entire run of the film series. Harris took the role to please his 11-year-old granddaughter, but unfortunately, Harris passed away before the release of the third film. Ian McKellen was offered the role, but it ultimately went to actor Michael Gambon, who played Dumbledore in all of the remaining films.
