Trivia

In Wes Craven's A Nightmare on Elm Street (1984), Heather played a 15-year-old girl. In a particular scene, after her character has experienced some bizarre events and is rather beaten down, she looks in a mirror and says, "God, I look 20 years old." The joke here is that even though Heather was playing a 15-year-old, she was actually 20 years old.
