Following an argument with his brother Stevie briefly strangles himself by wrapping a game-pad cord around his neck and pulling it tight.
Stevie is played by Sunny Suljic who was probably 12 at the time of filming. In the scene he pulls the cord really tight and even though it only lasts a few seconds it's a really arresting moment in the film.
Stevie is topless at this moment so I don't think there is any fakery going on, so my question is: How was this filmed? How is a 12 year old child allowed to strangle themselves for a movie? What precautions would the production take in this famously litigious country and in an industry where minors are heavily protected?
