The ‘Withnail’ cult shows no sign of waning. Writer/director of the 1987 movie Bruce Robinson spent some of lockdown discussing the film while co-star Richard E Grant posted regular line-readings on social media. And now there’s news of a long-awaited, Robinson-endorsed stage play.

So Toby Benjamin’s excellent ‘From Cult To Classic’ seems to have arrived at the perfect time. Authorised by Robinson and written with his full co-operation, it assembles a veritable cornucopia of ‘Withnail’ info.

The brilliantly blunt Robinson foreword almost had movingtheriver punching the air with excitement. Elsewhere letters from his personal collection show correspondence around the film’s financing and script editing. There are anotated script pages, detailed location administration and premiere tickets. We even see Robinson’s London to Cumbria train tickets for the shoot. Richard Curtis and Richard E also donate personal letters.

There are brilliant on-set photos, many by official snapper Murray Close, some donated by Robinson and the cast (including a great one of a clearly mullered Ringo Starr). All the main cast members give long, interesting interviews, as do many key bit-part players (The Irishman, the ‘Get in the back of the van!’ cop, Farmer Parkin) and the hairdresser, stills photographer, makeup artist, cinematographer, production manager, costume designer and soundtrack composers Rick Wentworth and David Dundas. We even hear from the owner of Crow Crag (Sleddale Hall).

There are a few minor quibbles – the book is dotted with ‘celebrity’ endorsements of the film but you’d be hard pressed to recognise any of them, outside of Matt Johnson, Charlie Higson and Diane Morgan, and no biographies are provided. Also the book’s ‘distressed’ interior design will probably divide opinion.

But if you’ve seen ‘Withnail’ more than once, you have to have this book. Absolutely unreservedly recommended to scrubbers and terrible c*nts everywhere.
