This 1987 black comedy written and directed by Bruce Robinson and based on his life in London in the late 1960s, is one of Britain's biggest cult films thanks to it's use of period music (it features a rare appearance of the 1968 Beatles song "While My Guitar Gently Weeps" which was written and sung by George Harrison, and included in the soundtrack due to Harrison's involvement as a producer), quotable dialogue, and a tour de force performance from Richard E. Grant as Withnail, probably one one of the most iconic figures in modern films. The movie follows two unemployed actors, Withnail and "I" (portrayed by Paul McGann) who share a flat in Camden Town in 1969. Needing a holiday, they obtain the key to a country cottage belonging to Withnail's eccentric uncle Monty (Richard Griffiths), where their weekend away proves less recuperative than expected. Ralph Brown plays Danny the drug dealer who rolls and smokes the Camberwell Carrot, the ultimate joint. Despite all the boozing and drug taking, Grant was a teetotaller with an allergy to alcohol. He had never been drunk prior to making the film, so Robinson forced him to go on a drinking binge so he could experience inebriation and a hangover in order to make his portrayal more believable.
