Bond girls are often victims rescued by Bond, fellow agents or allies,
villainesses or members of an enemy organisation; sometimes, as with
many 'pool' scenes, they are mere eye candy and have no direct
involvement in Bond's mission.
The role of a Bond girl is typically a high-profile part that can give a
major boost to the career of unestablished actresses (for example Jane
Seymour, Rosamund Pike), although there have been a number of Bond girls
that were well-established prior to gaining their role (for example
Honor Blackman, Diana Rigg, Halle Berry).
Furthermore, Academics have
analysed hours of Bond movies in a bid to discover what sort of woman
the MI6 spy goes for and the results show that out of 195 female
characters, 59% are brunettes. They tend to have American accents and
carry guns. The other interesting fact that came out of this "research"
is that the blondes do not get Bond's corny one liners...
