20 Harry Potter Actors Who Are No Longer With Us

7. Alfred Burke - Armando Dippet

Alfred Burke is one of the least noticeable actors in Harry Potter, thanks to the way he's portrayed in his only appearance. He played Professor Armando Dippet who was Headmaster of Hogwarts before Albus Dumbledore.

As such, he appears in The Chamber Of Secrets during the flashback sequences taking the film back to Tom Riddle's time at the school. Burke's face can actually only be glimpsed for a brief moment, and he wasn't as bald as the book description suggested he should have been.

Burke was an RSC veteran - like so many other Potter stars - and had numerous credits over decades, including Public Eye, and playing Long John Silver in the 1977 Treasure Island mini-series.
