The keyword term functions as a noun phrase. It is used to identify a specific person, the character Dun Meng, who was portrayed by the actor Jimmy O. Yang in the 2016 film Patriots Day.
In the film, which dramatizes the 2013 Boston Marathon bombing and the subsequent manhunt, Dun Meng is a Chinese immigrant and entrepreneur. His character is central to the narrative's turning point. After being carjacked by the perpetrators, Tamerlan and Dzhokhar Tsarnaev, Meng is held hostage in his own vehicle. He manages a critical escape when the brothers stop at a gas station. His subsequent call to the police provided law enforcement with the exact location and description of the stolen vehicle, enabling them to track the suspects to Watertown, Massachusetts.
The character is based on the real-life individual of the same name whose courageous actions were instrumental in the apprehension of the bombers. The portrayal highlights the role of an ordinary civilian in a major counter-terrorism event, demonstrating how quick thinking under extreme duress directly contributed to the resolution of a city-wide crisis. For actor Jimmy O. Yang, known primarily for comedic roles, this dramatic performance was a significant and widely noted part of his career.
