15) Shirley Henderson in Harry Potter and the Chamber of Secrets (2002)

Shirley Henderson was 36 years old when she acted as Moaning Myrtle, the ghost of 11 years, in Harry Potter and the Chamber of Secrets. She was rather old for the character, but her high-pitched voice, combined with the loneliness of Myrtle, made her one of the most unforgettable characters in the movie.
Her performance had the right balance: Moaning Myrtle's emotional depth against the seeming childishness of her personality. With the ability to portray Myrtle's emotional vulnerability and sadness, age was not a hindrance in her captivating performance.
