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 Château 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.
