It is, nonetheless, an unexpected direction for an actor — particularly one so prolific, so apparently committed to maintaining a steady stream of work. Ironically enough, Grant’s career was launched when he starred as an actor who couldn’t even get an audition, let alone a part, in Bruce Robinson’s 1987 film Withnail & I. As so often, however, overnight success looks simpler in hindsight. At the time, ‘they said the title was unpronounceable,’ he recalls now. ‘It had no women in it, no car chases, no Crocodile Dundee, which was the big hit of that year, nobody that anybody had heard of and no plot.’ After four weeks at the Odeon Haymarket, it shuffled off, but video and DVD releases made it a student cult (I should know: I was in its generational sweet spot, and still occasionally shout, ‘We’ve gone on holiday by mistake,’ or call for ‘the finest wines available to humanity’) and, over time, an acknowledged great of British film-making. Grant’s electrically manic, comically menacing performance — in a role turned down by Daniel Day-Lewis — is mesmerising, unforgettable. ‘It gave me my entire career,’ he says simply. ‘I owe everything to it and to Bruce Robinson.’
