The 2011 UK DVD and Blu-ray release has some of the credits in the opening titles reworked to remove the "Associated Britsh-Pathe Limited presents" credit and accordingly the titles appearing from "A Hammer Film Production" to the title of the film appear in a different synchronized order and accordingly have been extended to appear longer on the print by a few seconds so that the title of the film still appears at the same music clash points as intended.
