Avengers: Endgame is definitely an emotional movie, but one fan in China may have been hospitalized due to hyperventilation caused by uncontrollable sobbing.

According to WFMY News 2, a Chinese outlet reports that a 21-year-old woman in an unspecified region of China was sobbing uncontrollably during the film. After Endgame ended, she found herself "short of breath and her hands and feet felt numb." She was then brought to an emergency room, where a doctor determined her symptoms were a result of hyperventilation.

The woman's symptoms are reportedly now under control. At this time, it's unclear if this story is indeed true, as the woman's reaction seems particularly dramatic.

Endgame is one of the most anticipated movies of all time, as evidenced by its box office receipts. The movie is on track to become the first to ever break $1 billion in its opening weekend.
