ShreyaDolores Umbridge
Hands down Madam Undersecretary Professor Dolores Jane Umbridge was the worst and most detestable teacher in the history of all wizarding world and muggle teachers. She had the capability of putting even Dumbledore on edge with her short figure, high pitched tone and overflow of pink in her aura. She was herself a half-blood but propagated the removal of all Muggle-borns from the wizarding world. Giving her obsession with cats, it is no surprise that it was her Patronus too. She played the Ministry agent in Harry’s 5th year at Hogwarts and made the lives of students a living hell. But the Weasley brothers, Fred and George taught her a good lesson and nothing was more satisfying in Order of the Pheonix than the scene where she is taken away by centaurs and tortured!
Imelda Staunton
It is the mark of a great actress when they can entice strong emotions in the heart of the audience. Dolores Umbridge was supposed to be hated and Imelda played the character so well that she made the character unforgettable. She had an active acting and stage career before the idea of Harry Potter was even conceived. He has been trained at the Royal Academy of Dramatic Art and has performed in multiple numbers of plays and musicals. She has won 3 Olivier Awards, three of which for Best Actress. It was for the movie Vera Drake in 2004 that Staunton gained critical acclaim and also won the BAFTA Award for Best Actress in a Leading Role.
Moaning Myrtle
In the whole series Myrtle keeps crying about her death but for some reason, she never garners pity from readers and viewers, possibly because of her flirtatious behavior with every living boy she came across. It was as if death gave her license to pry into their personal business. Like other girls, she had a massive crush on Harry! Her real name was Myrtle Elizabeth Warren and she was the muggle-born victim of Tom Riddle’s Basilisk when the Chamber of Secrets was opened for the first time and she belonged to Ravenclaw. Since then she haunted the washrooms in Hogwarts and took offense if anyone talked to her as if she was dead (which to be fair to everyone, she was).
Shirley Henderson
Shirley Henderson was a name known to many even before her role as Moaning Myrtle. She is a Scottish actress and is famous for her role in Bridget Jones’ Diary film series where too, she can be found moaning mostly. Coincidence? We don’t think so. It is probably her expertise in crying that landed her the role of Myrtle in the first place. Other films of hers include Anna Karenina, Frozen, Miss Pettigrew Lives for a Day and also Netflix film Okja. Recently, like her other Harry Potter counterparts, she has been focusing on her theatre and stage career. She has been part of the stage productions of Romeo and Juliet and The Winter’s Tale among others.
Sybill Trelawney
This half blood Divination teacher is one of those characters which have not gotten the attention they deserve. Probably because of her habit of predicting the death of every other student. But this was the woman who set the wheels of Harry hunt by Voldemort in full throttle motion because she prophesied his vanquishment by the ‘Chosen One’. She also predicted the return of Peter Pettigrew and the return of the Dark Lord. Not many know this but she belonged to the Ravenclaw house, not surprising given her curious Seeing skills. She might have appeared like a nincompoop but the fact is Sibyl plays an important role in Hogwarts and lives of wizards and witches and the wise Dumbledore realized that.
Emma Thompson
Sibyl Trelawney was just one in the list of the roles that Emma Thompson played as an enigmatic and peculiar woman. She is one of most acclaimed actresses in Britain and is also a screenwriter. She is most famous for playing witty characters. No doubt she is so skilled she was born to parents who were actors themselves. She won the BAFTA TV Award for Best Actress for her work on two BBC TV series-Fortunes of War, and Tutti Frutti.
