The Restoration department at Pinewood were working from the original 35mm camera negative of Scum, which was originally released in 1979.
In a review by Kevin Yeoman from Blu-ray High-def Digest, he said:
“There has been a significant effort put forth in getting the film on Blu-ray in the best possible shape, and I'm pleased to say that the team at Pinewood Studios were diligent in their task and have come up with a tremendous transfer that doesn't go too far with the digital manipulation or scrubbing that can otherwise upset the restoration process. Here, the image has been thoroughly cleaned, leaving no trace of noise, scratches or dust anywhere on the final product. Additionally, there are no hints of screen flicker or distortion of any kind. Most impressive, however, is that the image still retains its filmic quality; there's plenty of grain on.”
Scum, now available on Blu-ray and DVD, tells the story of Carlin (Ray Winstone, The Departed), a new reform school inmate with a reputation as a hard case. The authorities encourage gang leader Pongo (John Blundell) to humble Carlin, but he beats Pongo down and takes over the mantle of “Daddy”. The guards institute a reign of terror and neglect, with Carlin emerging as an unlikely leader.
