For those who don't want to read the whole thing, here are the passages on 'Withnail and I':
"That last film, with a life-altering performance from Grant as the duplicitous, permanently parched fop, superbly assisted by McGann as his innocent, mesmerised companion, draws on Robinson's experiences as a chronic alcoholic and resting actor, living in squalor in Camden Town.
"Withnail and I embodies the popular (if misguided) British belief that there is a curious nobility to the art of remaining permanently hammered. It embodies that perverse sense of heroism much in the way that The Great Escape has come to symbolise a more orthodox form of bravery. The obsession Withnail and I inspires in every new generation of aspirant bohemians has led to its being called "the definitive cult movie", a description unworthy of his masterpiece, whose dialogue – driven by what the writer Kevin Jackson called its "ferocious verbal inventiveness" – verges, as Bruce Robinson's writing often does, on the poetic."
