2018 horror film Hereditary quickly gained a reputation for being absolutely terrifying.
Described as 'the scariest film of the year' even before its release, the movie contains a number of bloodcurdling scenes that will definitely haunt your dreams for nights after watching it.
It's also had a long-term impact on star Milly Shapiro, who played Toni Collette's daughter Charlie, a spooky character that loses her head (literally) and is central to the film's biggest twist.

Now 18, Milly shared a video on TikTok sharing the effect negative comments about her appearance in the movie had on her.
"Being in a movie and playing a character where they purposely made you look your worst and then millions of people seeing it," Milly wrote, with the video playing a song track about something impacting you mentally.
"I just remember when the trailer came out and one of the top three comments was about how ugly I looked hahahahhahahajahaahjzjsja," she said in the caption.

Milly was born with a genetic condition known as Cleidocranial Dysplasia (CCD).
It affects the development of bones and teeth.
CCD often causes partly or completely missing collarbones, a narrow pelvis and a shorter stature. It also causes the spaces between the bones of the skull to take longer than expected to close.
