Moaning Myrtle in 'Harry Potter' 'Memba Her?!

Scottish actor Shirley Henderson is best known for playing the ghostly girl Moaning Myrtle -- whose dramatic antics in the bathroom ... and later in a bubbly bathtub ... help the young magicians ward off dark spirits -- in the 2002 film "Harry Potter and the Chamber Of Secrets" and the 2005 installment "Harry Potter and the Goblet Of Fire."

Before her role on the fantasy films Henderson was cast as the party girl who still lived at home Gail in "Trainspotting" and the shy friend Jude in the three "Bridget Jones' films.
