The article looks at how actor Dennis Hopper, particularly during and after his work on 1969's *Easy Rider*, became emblematic of the excessive drug culture that swept through 1960s and 1970s Hollywood, with his influence and habits reportedly extending well beyond his own circle. It matters as a piece of film history and cultural commentary, illustrating how one figure's off-screen behaviour became entangled with the mythology of an era-defining counterculture film and, by extension, a broader shift in American attitudes towards drug use.

The piece draws on accounts of Hopper's own admissions and recollections from collaborators about the scale of drug consumption surrounding him during this period, describing behaviour that went well beyond typical excess. It situates this within the wider context of New Hollywood's countercultural moment, when *Easy Rider* itself became a touchstone for drug-fuelled road-trip cinema, suggesting Hopper's personal conduct helped normalise and popularise such indulgence far beyond the film industry itself.
