Scottish actor Shirley Henderson has shed new light on one of the Harry Potter franchise’s most discussed pieces of casting, recalling that she was in her late 30s when she auditioned to play bathroom ghost Moaning Myrtle, a character written as a 14-year-old schoolgirl. The story resurfaced after trade publication Variety noted that she was 37 at the time of the audition for Harry Potter and the Chamber of Secrets, prompting fresh debate about age and realism on screen.
Henderson says she hesitated when she was first invited to read for the role, unsure she could convincingly play a teenager. She had not yet read the Harry Potter books and relied on a family member’s enthusiasm to gauge the scale of the phenomenon. In recent interviews she recalls a casting director encouraging her to go ahead and simply avoid mentioning her age. She arrived at the audition in a white shirt, black skirt and ponytail, deliberately dressed as a schoolgirl and privately thinking the whole exercise felt faintly ridiculous. Months passed before she heard back; then the filmmakers offered her the part.
Looking back, Henderson has suggested that the age gap was softened by the nature of the character. Myrtle is a ghost who died decades before Harry arrives at Hogwarts, and the actor has described her as an older, emotionally frozen presence stuck in a teenager’s body. With the performance filtered through stylised movement, heightened vocal work and visual effects, she argues that audiences focus on the character’s misery and mischief rather than the performer’s real age.
News of her age at the time of casting has sparked amusement and surprise online, where fans have shared stills and trivia pointing out that she is thought to be the oldest performer to play a teenage Hogwarts student. The reaction feeds into a recurring conversation about the tradition of adult actors playing adolescents, a practice that some viewers defend as an industry necessity and others criticise as a distortion of teenage representation.
Henderson’s reflection comes at a time when her career remains busy on stage and screen, with recent releases and television work joining a filmography that spans independent dramas, studio comedies and acclaimed theatre roles. She has said that the Harry Potter films did little to change everyday recognition, since her best-known character appears as a pale, wailing spectre rather than her own face, yet the latest discussion underlines how enduring even a brief appearance in the series can be.
