 After the deaths of Sir Percy(Aubrey Morris) and Armstrong, the Churchill   flashback the love scene between Carlsen and the Space Girl is cut to the   bone. Likewise the scene with the Infected PM (Peter Porteous) and his   Secretary, Miss Haversham(Katherine Schofield) has had huge chunks cut out   e.g. the PM being told of The Home Secretarys demise. Plus there are lines   reactions closeups omitted here where and everywhere. The 101 Min version   had some more zombie mayhem.
