This movie should not be mistaken as a budget imitation of a James Bond film, as it possesses it's own distinctive characteristics. Yet, for it's time (1969) it is just as adventurous and entertaining with Richard Johnson performing the role of (Bulldog) Hugh Drummond, similar to your James Bond Secret agent, but with a touch of humour and to some extent, a bit of sarcasm. Like Bond, Drummond is well skilled, serious and intelligent and is out to investigate what is behind a series of murders disguised as accidents, that are carried out by what appears to be beautiful young women (hence it's title Some Girls Do). Robert Morley performs the part of Miss Mary and is later found dead after having given classes to potential chef students in perfecting the art of cracking eggs open into a bowl.
Drummond is also targeted when flying a glider and is meant to crash down when his parachute has been tampered with by the beautiful robotic women who watch from below, but manages to skillfully and successfully release open the parachute, landing down safely as if nothing had happened.. A fine performance by Sydney Rome as the typical James Bond type girl, but Drummond is not at all fooled by her pampering and charming behaviour, as he is very intelligent in sensing her motives.. She does play the bimbo but is very cunning, as most Bond style girls are.
In a nutshell I did enjoy this movie and am not surprised that any criticisms are really more to do with it's comparisons to modern released movies. However, I am very surprised that the character of Bulldog Drummond was not pursued in later years like with remakes of `A Thomas Crown Affair', `The Avengers', `The Saint' etc. I believe that the character of `Bulldog' Drummond could have been further modernized and made into a big hit in the late 1970's upto the 1990's with newer adventures, as it had all the charm and character of serving action/adventure style movies, but on a larger scale. I would have kept one foot in the 1960's and another one in the 1990's keeping that style in an evergreen sense.
