Overview

• A Hollywood Reporter profile describes a near-physical clash in which Costner allegedly lunged at Bentley during a tense scene, prompting a brief production shutdown.
• Bentley’s representative confirmed a work-related argument occurred during a difficult scene and said the matter was discussed and resolved, while Costner’s camp did not comment.
• Sources say the dispute began when Costner urged Bentley to deviate from Taylor Sheridan’s script, and Bentley refused, emphasizing his commitment to Sheridan’s vision.
• Witness accounts report Kelly Reilly was in tears and describe the incident as a “line in the sand” after which many cast members sided with Sheridan over Costner.
• Coverage links the escalation to Costner’s departure from later episodes of the series and situates it within broader scrutiny of his Horizon project and related lawsuits.
