What is the fine-grained topic of the following text: There’s Kino digging up the forgotten Sidney Lumet film The Group, the Warner Archive Collection finally giving The Thing from Another World the Blu-Ray it deserves, Criterion upgrading its Berlin Alexanderplatz box set, Shout Factory continuing to mildly upgrade MGM titles with a 4K restoration of Four Weddings and a Funeral, and Arrow finally bringing us a decent-looking stateside Blu-Ray of Audition. Only return the topic.
Restoration and upgrade of classic films to Blu-Ray and 4K formats by various film distribution companies.
