Some Girls Do is a 1969 British comedy spy film directed by Ralph Thomas. It was the second of the revamped Bulldog Drummond films (following 1967's Deadlier Than the Male) starring Richard Johnson as Drummond, made following the success of the James Bond films of the 1960s. Some Girls Do even featured a white Aston Martin DB5, the same marque used by Bond. Plot A series of inexplicable accidents befall the development of the world's first supersonic airliner, the SST1 – a man falls victim to a homicidal air stewardess (an uncredited Maria Aitken) and two women (Yutte Stensgaard and an uncredited Joanna Lumley) perform separate acts of sabotage during tests. The Air Ministry calls on Hugh "Bulldog" Drummond (Richard Johnson) to investigate. Aided by ditzy American blonde Flicky (Sydne Rome), Drummond uncovers a plot by criminal mastermind Carl Petersen (James Villiers), who stands to gain eight million pounds if the aircraft is not ready by a certain date. Petersen, assisted by beautiful but deadly assassins Helga (Daliah Lavi) and Pandora (Beba Lončar), has developed a number of robots: beautiful girls with electronic brains to help him sabotage the SST1 project by means of infrasound (sound waves with too low frequency to be detected by the human ear) which can be directed at people or objects with devastating results. After the initial sabotage attacks by Peterson's robots, Helga and Pandora begin systematically murdering various people associated with the SSTI, such as engineer Dudley Mortimer (Maurice Denham) and Miss Mary (Robert Morley), a spy who runs a cooking class as a front for his activities. Helga makes contact with Drummond at a shooting party, and attempts to kill him by planting a bomb in his telephone after sleeping with him. Then Helga and Pandora try to kill Drummond again by crashing into his glider. The ripcord from his parachute was sabotaged but Drummond manages to manually open his parachute and escape death. The trail leads Drummond to North Africa, following up on a lead on an infrasound-powered powerboat, where he is assisted by Peregrine Carruthers (Ronnie Stevens) from the British Embassy. Pandora kills the boat owner with a miniature infrasound device, but is thwarted in her attempt to steal the boat. Drummond and Peregrine decide to drive the powerboat in a scheduled race: Helga and Pandora also participate in the race and successfully capture the men and the boat, delivering them
