The 2012 UK Blu-ray Disc released by Studio Canal features digitally enhanced special effects. The makers of the Blu-ray claim to complete shots which had never been finished due to budget reasons: - Matte shot of Simon's mansion with the Observatory dome has been replaced with a CGI background. - During the ritual at the climax of the movie a lightning has been replaced with a new CGI lightning. - Spider sequence: Shadow for the spider has been added, some matte shots enhanced, and digital smoke added when the spider is sprayed with holy water. - The Angel of Death sequence: A light effect is illuminating the door to cover the poor original optical effect when the angel rides through the door. The close up of the Angel of Death has a new background with flames as the original intended shot was never finished. - The matte shots of Charley Grey's death in the fire have been digitally corrected as there were optical errors in the layers of the matte shots. - Several other matte shots have been improved by removing matte lines.
