What John Sayles film depicts a deadly event from the mine wars?

The film that depicts a deadly event from the mine wars is "Matewan." This movie, directed by John Sayles, is based on the real-life events surrounding the Matewan Massacre, which occurred in 1920 in West Virginia. This incident was a significant conflict between coal miners and the coal companies, highlighting issues such as labor rights, unionization, and the struggle of workers against oppressive conditions.

"Matewan" effectively portrays the historical context of the mine wars through its rich narrative, character development, and attention to the socio-economic factors at play during that turbulent period in West Virginia's history. The film's depiction of these events provides viewers with insight into the hardships faced by miners and the violent confrontations that characterized the fight for labor rights in the early 20th century.

The other films listed, while notable in their own right, do not focus specifically on the mine wars or events directly related to labor disputes in the coal industry, which makes "Matewan" the correct choice for this question.
