After the unexpected loss of Armendáriz, production proceeded, experiencing complications from uncredited rewrites by Berkely Mather during filming. Editor Peter Hunt set about editing the film while key elements were still to be filmed, helping to restructure the opening scenes. Hunt and Young came up with the idea of moving the Red Grant training sequence to the beginning of the film (prior to the main title), a signature feature that has been an enduring hallmark of every Bond film since. The briefing with Blofeld was rewritten, and back projection was used to refilm Lotte Lenya's lines.
