Cars fly, trees fight back, and a mysterious house-elf comes to warn Harry Potter at the start of his second year at Hogwarts. Adventure and danger await when bloody writing on a wall announces: The Chamber Of Secrets Has Been Opened. To save Hogwarts will require all of Harry, Ron and Hermione’s magical abilities and courage.
This movie contains 48 potentially triggering events.
No one physically harms a family member (though it's heavily implied that the Dursleys abuse Harry, and that Lucius Malfoy abuses his son), but Lucius Malfoy frequently physically harms his servant.
Dobby steals Harry's unread mail in order to make Harry think that no one is writing to him and his friends no longer care about him. A character loses their memory and is told lies about who they are. An 11-year-old girl is lied to and emotionally manipulated by a man.
Yes, an arm is broken, and then in an attempt at healing the injury, the bones in the arm disappears all together. The boneless arm is then folded in half, which is pretty disgusting.
Dobby mentions that he slammed his fingers in a door as an act of self-harm, and there is a closeup of his damaged and bandaged fingers; this happens soon after he visits Harry in the hospital wing at night. The bones of Harry's arm and hand are removed after he breaks his arm during quidditch.
No, but a large part of the story is males arbitrarily hiding in a girls’ bathroom to do something illegal (drug Crabbe and Goyle and steal their likeness with a potion). Nobody is trans-coded but this plot point is uncomfortable in hindsight since JKR is infamous for spouting transphobic propaganda, including about trans women in women’s bathrooms.
Dobby the house elf harms himself systematically as self inflicted punishment for disobedience or disrespect against his masters. I don’t know why people are selecting ‘No’ on this; it’s a major part of Dobby’s whole situation, and is revisited multiple times throughout the film.
An 11 year old girl is possessed by the memory of a teenage boy who forces her to do things like kill chickens and write messages on walls in blood. She blacks out during these episodes and wakes up covered in blood/feathers/etc, so starts to worry that she is responsible for those things as well as the attacks on students.
Ginny does not have DID, however, she is possessed, and the books in particular go into DID-esque symptoms of lost time and dissociative amnesia, and everything she does while possessed is violent or destructive.
Once again the classic mistake of people thinking body dysmorphia and body horror are the same thing so I'll clear up some misconceptions; no there is not any body dysmorphia in this movie to my knowledge, the polyjuice potion scene may contain some body horror but to my memory no characters show signs of discomfort over their real bodies throughout the movie
Draco calls Hermione a “mudblood”, which is revealed to pretty much be a slur against wizards born from non magical parents. This is not seen in a positive light and Hermione’s friends defend her.
