Remember I told you about Luke Johnson, the ex-Channel 4 chairman who also presided over the demise of Borders UK, warning High Street book shops are doomed? Curzon Artificial Eye, the arthouse distributor/exhibitor, is building a cinema inside Waterstone’s flagship Piccadilly store. Trade magazine The Bookseller says more Curzon/Waterstone’s bookshop cinemas are planned. The exhibition chain already runs one cinema in Wimbledon out of an HMV record store. HMV owns Waterstone’s. Ross Fitzsimons, group strategy director of Curzon Artificial Eye, says 20 more HMV joint ventures are planned over the next five years. Waterstone’s declined to comment.
