Up until that point, there is no evidence or data to suggest that Korean actors cry more than actors from other countries as a general rule. The frequency of crying or emotional expression in acting is not typically tied to a specific nationality or culture.
Acting styles and preferences can vary widely across different countries and cultures. Some actors may have more emotionally charged roles that require crying scenes, while others may not. The portrayal of emotions in acting is influenced by the script, character, director's vision, and the actor's individual approach to their craft.
In Korean dramas and films, there are instances of emotional scenes that involve crying, which has become a significant aspect of certain genres like melodramas. However, this doesn't mean that Korean actors, as a whole, cry more than actors from other countries.
Actors from different cultural backgrounds may have unique approaches to expressing emotions on screen, and it's essential to recognize that this diversity is what makes global cinema and television so rich and intriguing.
