The finished film replaced the nude scene with milder shots showing Sharon stepping into and out of a shower. A subplot concerns the Rosses' attempts to have a child and Glenn's discovery that Sharon has been taking birth control pills. The original script described Sharon as the daughter of a United States senator and had her pursue an affair with EUROSEC public relations officer Carlo Monetti. In the finished film, this character, played by Franco De Rosa, is renamed Paulo Landi and appears only briefly; the affair is implied in one scene but not explored further. In a deleted scene, Glenn finds Paolo and Sharon in bed together at the Rosses' villa and throws them both into a swimming pool. Patrick Wymark played Jason Webb, the director of EUROSEC. Wymark was cast for his performance as the antiheroic businessman John Wilder in the TV dramas The Plane Makers and The Power Game; he was described in publicity material as "John Wilder (2069 model)". According to Anderson, Wymark's heavy drinking caused him to slur his lines: in one scene, the actor "had to list these explanations ... and on take after take he couldn't remember that 'two' followed 'one'. We had to do it over and over again". Anderson's biographers, Simon Archer and Marcus Hearn, consider Wymark's portrayal of Webb to be the film's standout performance. The original script described Webb as a former Minister of Technology who is romantically involved with his secretary, Pam Kirby (Norma Ronald, who had played Wilder's secretary in The Plane Makers and The Power Game). The supporting cast included George Sewell, Philip Madoc and Ed Bishop, who respectively played EUROSEC operations chief Mark Neuman (Mark Hallam in the original script), Dr Pontini, and NASA representative David Poulson. Sewell and Madoc had both appeared in The Power Game. Poulson was to have been played by Peter Dyneley, but the role was re-cast as the producers felt that Dyneley bore a strong resemblance to Wymark and that the scenes featuring both actors would cause audiences to confuse the characters of Poulson and Webb. Filming Filming began on 1 July 1968 at Pinewood Studios and ended on 16 October. The exterior of the EUROSEC Headquarters was represented by Neptune House in Borehamwood, Hertfordshire (now part of BBC Elstree Centre), while Heatherden Hall appeared as the old Jason Webb's nursing home. In September, the crew travelled to Albufeira, Portugal
