Special effects producer Mike Tucker was reminded of the James Bond film "The Man with the Golden Gun" when reading the scene in which the Nestene's lair is blown up, and sought to display it as a major effect. The production team built a one-sixth scale model of the paper mill where the explosions were filmed. Tucker did a model explosion for the destruction of Henrik's as well, although that was only for the roof; the rest was done by CGI. The production team considered doing the explosion practically, but that would have been too expensive. Model work was filmed on 16mm film at the BBC Model Unit on Kendal Avenue in London from 15 to 16 September.
