Helena Bonham Carter

Helena Bonham Carter is an acclaimed English actress. In the context of the Harry Potter universe, she is celebrated for her iconic portrayal of the fanatical and sadistic Death Eater, Bellatrix Lestrange, in the film adaptations. She first appeared in the fifth film, Harry Potter and the Order of the Phoenix, and her performance became one of the most memorable character interpretations in the series.

Bonham Carter took on the role of Bellatrix Lestrange starting with the 2007 film adaptation of Harry Potter and the Order of the Phoenix. The role had originally been given to actress Helen McCrory, who had to step down due to her pregnancy. McCrory was later cast in the role of Bellatrix's sister, Narcissa Malfoy. Bonham Carter portrayed Bellatrix in four films. She also made a unique contribution in Harry Potter and the Deathly Hallows – Part 1, where she played Hermione Granger who had transformed into Bellatrix via Polyjuice Potion. In these scenes, she effectively mimicked Emma Watson's mannerisms as Hermione, who was awkwardly and nervously impersonating the fearsome Death Eater.

Bonham Carter's interpretation of Bellatrix Lestrange is noted for its manic energy, unhinged glee, and theatrical cruelty, which slightly differs from the colder, arrogant cruelty depicted in the novels. Her on-screen presence was defined by wild, tangled hair, dark gothic attire, and a perpetually crazed expression. Key moments from her performance include:

Her portrayal solidified the character's image in popular culture as one of the most terrifying and visually distinctive villains of the series.
