Robinson??s companion through the worst of it was MacKerrell. The scene where they drink lighter fuel in the film comes from something MacKerrell actually did: he couldn??t see for days afterwards and Robinson suspects it might have caused the throat cancer that eventually killed his friend.
Robinson knew it had to end when MacKerrell returned from a trip home to Scotland armed with bottles of a drink ?? 200 per cent proof, Robinson claims ?? that distillery workers made by sticking used whisky filters into spin driers.
Deranged by the drink, Robinson and MacKerrell, armed with a hammer and an artificial leg, smashed one of the walls of their house down. It still took another six months for Robinson and MacKerrell to work up the will go their separate ways.
Although his friends were fascinated by him, MacKerrell??s career ?? like Withnail??s ?? was one of overwhelming obscurity, best summed up by the fact that the IMDB spells his name wrong and lists him as an actress.
??Give me a fucking pre-med you fuckers, I??m a personal friend of Sir Lancelot Spratt.?? These words of frustration were the last to issue from Vivian??s wonderful classically-trained voice. Forcing himself upright on the hospital trolley, he saluted his friends before being wheeled into the operating theatre for the removal of his voice-box; a procedure he later dismissed flippantly as ??getting a Jack Hawkins??. His final months would reveal a man of extreme courage, and a refusal to curb his excesses for anyone. Unable to swallow, he was forced to pump alcohol via a syringe directly into his stomach and spent his last few weeks propped up on Moroccan cushions listening to his beloved Elvis, refusing any nourishment other than dry sherry.
He died in 1995 from throat cancer.
