EXCLUSIVE From Deadline|London editor Tim Adler: Cinema chains including Cineworld, Odeon and Vue have all been able to upgrade to digital free of charge thanks to the British government. Whereas other exhibitors have had to spend hundreds of thousands of pounds installing 3D digital projectors and screens, only to see the big chains receive a massive leg-up on 3D courtesy of the public purse. It costs between ?70,000 and ?100,000 to convert each screen to digital. No wonder rivals to the Big Three think this is unfair competition.
