Around ten minutes of new footage were added for the New World adaptation, most of it at The Pentagon. New World originally planned to tap Lorne Greene as the star of these new scenes, but Randel suggested that casting Raymond Burr would be a good homage to "Godzilla, King of the Monsters!", as Burr had performed the same duty of starring in new American footage for that film. According to Randel, Burr was enthusiastic about the film when offered the role, but after being signed on he made several unusual demands. The new footage was shot over three days, but Burr was only on the set for the first day, and was adamant that he would work no more than eight hours, forcing the director to focus on shooting Burr only and save reaction shots for later. Burr also refused to memorize his lines, insisting that teleprompters be strategically positioned around the set instead, despite the logistical difficulties this presented for the crew. Burr also made clear that he took the concept of Godzilla as an anti-nuclear allegory seriously and would not treat it as a joke. Warren Kemmerling also refused to do comic material, though not out of respect for Godzilla, so the script was revamped to reassign all the comedic lines to Travis Swords.
