Legacy
It is widely regarded as being one of the greatest British films ever made, and its influence has been cited by several filmmakers as directly inspiring their work, among them Shane Black's The Nice Guys, James Ponsoldt's The End of the Tour, Todd Sklar's Awful Nice, Jay and Mark Duplass's Jeff, Who Lives at Home, John Bryant's The Overbrook Brothers, David Gordon Green's Pineapple Express, Alexander Payne's Sideways, and Tom DiCillo's Box of Moonlight.
In 1999, the British Film Institute voted Withnail and I the 29th greatest British film of all time. In 2001, Withnail and I was ranked 38th in Channel 4's 100 Greatest Films poll. In 2008, the film was ranked number 118 in Empire's 500 Greatest Films of All Time list. A 2009 poll by The Guardian among film critics and filmmakers voted it the second best British film of the previous 25 years. In 2011, Time Out London named it the seventh-greatest comedy film of all time. In a 2014 poll, readers of Empire voted Withnail and I the 92nd greatest film.
In 2016, Games Radar voted Withnail and I the 16th greatest comedy film of all time. In a 2017 poll of 150 actors, directors, writers, producers and critics for Time Out magazine, the film was ranked the 15th best British film ever. The line "We want the finest wines available to humanity, we want them here and we want them now", delivered by Richard E. Grant as Withnail, was voted the third favourite film one-liner in a 2003 poll of 1,000 film fans.
There is a drinking game associated with the film. The game consists of keeping up, drink for drink, with each alcoholic substance consumed by Withnail over the course of the film. All told, Withnail is shown drinking roughly 9+1⁄2 glasses of red wine, one-half imperial pint (280 ml) of cider, one shot of lighter fluid (vinegar or overproof rum are common substitutes), 2+1⁄2 measures of gin, six glasses of sherry, thirteen drams of Scotch whisky and 1⁄2 pint of ale.
In 1992, filmmaker David Fincher attempted to create an unofficial reunion of sorts, when he attempted casting all three of the film's main characters in Alien 3. McGann and Brown appeared; however, Grant turned down his role, which eventually went to Charles Dance, who played the character of Clemens in the "spirit of Withnail".
In 1996, the Los Angeles Times reported the film (and the associated drinking game) had achieved cult status prior to its home video re-release in the United States.
In 2007, a digitally remastered version of the film was released by the UK Film Council. It was shown at over 50 cinemas around the UK on 11 September, as part of the final week of the BBC's Summer of British Film season.
In 2010, McGann said that he sometimes meets viewers who believe the film was actually shot in the 1960s, saying "It comes from the mid-1980s, but it sticks out like a Smiths record. Its provenance is from a different era. None of the production values, none of the iconography, none of the style remotely has it down as an 80s picture."
In 2025, British actor and comedian Reece Shearsmith dressed in Withnail’s costume throughout the 20th series of the UK TV show Taskmaster, including contacting original costume designer Andrea Galer to have a replica coat custom made.
