Withnail & I (1987)

Directed by Bruce Robinson

Two out-of-work actors -- the anxious, luckless Marwood and his acerbic, alcoholic friend, Withnail -- spend their days drifting between their squalid flat, the unemployment office and the pub. When they take a holiday "by mistake" at the country house of Withnail's flamboyantly gay uncle, Monty, they encounter the unpleasant side of the English countryside: tedium, terrifying locals and torrential rain.

As this film started to close out, I started to realise how taken I was with it. A 'film about a drunk' is not quite my cup of tea (or should that be '53 Ch√Ęteau Margaux?) without it doing something else as well, but it somehow caught my attention. And not only because it is the obvious inspiration for a whole host of comedic personas: Richard Griffiths' Vernon Dursley is literally identical to his Monty, and Ralph Brown's philosophising drug-dealer schtick can be easily seen in Noel Fielding and, perhaps, even Russell Brand.
