The intense effects from the strong Humboldt County cannabis forced the entire production to shut down for the day as she struggled with paranoia and hallucinations. She had no idea the joint was authentic until the high took hold hours later in her trailer.
The mishap took place during repeated takes of a key scene in which her character lights and smokes a joint. Locals from the Northern California area were hired to roll what were supposed to be fake props using tobacco or herbs. One of those joints turned out to be the real thing either through an honest mistake or perhaps a misguided prank and Dunst consumed the entire thing without realizing because she had eaten very little that day.
Once back in her trailer the symptoms escalated rapidly. Dunst began pacing back and forth and alerted the directors who investigated and confirmed the substitution. Production came to a complete stop while she waited for the effects to subside and she later recalled trying a peanut butter sandwich as a remedy.
Dunst first shared the full story during her 2017 appearance on Jimmy Kimmel Live where she recounted the paranoia and the decision to halt filming. In the interview she explained how she felt completely out of control and even considered seeking medical help at one point. Her candid retelling humanized the challenges of immersive filmmaking.
A short clip from Woodshock depicting the exact smoking sequence has now gone viral on X amassing millions of views since it was posted on April 19 2026. In the footage Dunst holds the unlit joint near her face with a calm expression then places it in her mouth lights it with a visible flame and inhales deeply before exhaling smoke as her eyes lower and her body relaxes into the moment. The 19 second excerpt perfectly illustrates the action that led to the real life incident on set.
Woodshock itself centers on a young woman grappling with grief who turns to cannabis and experiences hallucinatory effects in the process. The film marked the feature directorial debut of the Mulleavy sisters the fashion designers behind Rodarte. Dunst delivered a nuanced performance as the lead character Theresa despite the unexpected hurdle during production.
This marijuana episode offers a compelling glimpse into the unpredictable realities actors sometimes encounter when props mirror the subject matter too closely. It also prompts reflection on how high potency cannabis can produce strong reactions even in controlled settings and why clear protocols matter on every film set. As the story resurfaces just before April 20 it encourages thoughtful conversations about personal experiences with marijuana and the value of open storytelling from those in the spotlight.
