Zach Galifianakis favorite British cult comedy film is the legendary “Withnail & I,” a darkly comedic tale of friendship adored by actors like Paul Rudd and Colin Farrell as well. When discussing influential comedies, these actors have pointed to this 1987 classic as a standout, noting its unique place in the tradition of British cinema and quirky, conflicted friendships.
A Closer Look at “Withnail & I”
“Withnail & I” centers on two struggling actors, Withnail (Richard E. Grant) and Marwood (Paul McGann), navigating the hardships of 1969 London. Faced with ongoing poverty and limited opportunities, they spend their days in a cluttered, run-down flat, filling time and space with heavy drinking. Marwood, while managing to find occasional acting work, is an anxious and cautious presence who tries to keep things in check. By contrast, Withnail is an intense, self-absorbed character who is convinced the world is overlooking his supposed genius, resorting to manipulative and indulgent behaviors that put a strain on their friendship.
The story shifts when the pair decide to break free from their dreary routine by retreating to the countryside cottage of Withnail’s wealthy uncle, Monty (Richard Griffiths). Their planned escape quickly unravels as the unpredictable Monty and the unfamiliar, sometimes unfriendly locals turn what was meant to be a relaxing holiday into an ongoing series of misadventures. Combining elements from a comedy of errors and an offbeat character study, the film maintains its often bleak tone while delivering laughs that emerge directly from the two protagonists’ flawed relationship and their inability to break free from their circumstances.

The Dynamic Between Withnail and Marwood
The heart of the film lies in the unique chemistry shared by Withnail and Marwood. The plot itself may move slowly, but their constant push-pull dynamic carries the narrative, reminiscent of a downtrodden, more dysfunctional version of classic comedic duos. Withnail constantly disrupts their lives in pursuit of excitement or fulfillment, while Marwood, despite trying to set boundaries, often ends up reluctantly following. This relationship is one of toxic codependency—Withnail pressing forward heedlessly and Marwood suffering the consequences, providing comedic tension that drives the film forward.
Marwood, as the more morally grounded partner, continuously finds himself at a disadvantage, often bearing the brunt of Withnail’s reckless actions. His ongoing frustration and exasperation contrast sharply with Withnail’s theatrical bravado, making their friction both painful and hilarious to watch. The comedy thrives on their disastrous attempts at self-improvement, with Marwood’s efforts to control events inevitably clashing with Withnail’s self-inflicted chaos.
The casting choices further elevate the humor. Paul McGann delivers a reserved, measured performance as Marwood, acting as the audience’s anchor in the madness. However, it is Richard E. Grant’s interpretation of Withnail that leaves an indelible mark—his gaunt appearance, disheveled attire, and caustic delivery collectively shape a character both fascinating and tragic. Withnail’s self-destruction and inflated ego become hilarious and poignant, encouraging viewers to observe his decline with a mix of regret and amusement. Grant’s portrayal would go on to shape much of his later career, especially as he perfected the art of playing larger-than-life, self-important figures.

In examining the ongoing relevance of the film, it becomes a touchstone for stories of complicated male friendships that defy simple categorization. The connection between Withnail and Marwood is more than mere camaraderie; it hints at a level of intimacy rarely explored in cinematic portrayals of male relationships. This ambiguity makes the film resonant across generations and acting styles, inspiring nuanced performances in later works.

This acknowledgment reflects the film‘s continued impact on contemporary acting, particularly in its exploration of vulnerability in male ties and the blurred limits between supportive and destructive bonds.
