Not Sure. In & out of print on VHS for years, Sloane finally gets a much deserved DVD release. The picture seems much improved, crisper and sharper print than ever before and seems to have been cleaned up. Sound mix is mono but sounds average for it's type. The only problem I have with this is that the picture looks zoomed in, it is 16:9 but looks cropped at top and bottom, if it's been modified from 4:3 then I wish they'd just left it alone. The film itself is first class and does justice to Orton's text. Beryl Reid gives one of if not her best ever performance, the support cast are equally great. Benefits from repeated viewing.
