A Bond girl is a character (or the actress portraying a character) who is an attractive love interest and/or female sidekick of James Bond in a novel, film, or video game. Bond girls occasionally have names that are double entendres or puns, such as Pussy Galore, Plenty O'Toole, Xenia Onatopp, or Holly Goodhead, and are considered "ubiquitous symbol[s] of glamour and sophistication." There is no set rule on what kind of person a Bond girl will be or what role she will play. She may be an ally or an enemy of Bond, pivotal to the mission or simply eye candy.
Effect on career
The role of a Bond girl, as it has evolved in the films, is typically a high-profile part that can sometimes give a major boost to the career of unestablished actresses, although a number of Bond girls were well-established beforehand. For instance, Diana Rigg and Honor Blackman were both cast as Bond girls after they had already become stars in the United Kingdom for their roles in the television series, The Avengers. In addition, Halle Berry won an Academy Award in 2002--the award was presented to her while she was filming Die Another Day. Teri Hatcher was already known for her role as Lois Lane in the television series Lois & Clark: The New Adventures of Superman before she was cast in Tomorrow Never Dies. A few years after playing a Bond girl, she became one of the most highly paid actresses on television, starring in Desperate Housewives. Jane Seymour was an unknown when she was cast in Live and Let Die (the opening credits read "Introducing Jane Seymour"), later won an Emmy Award for playing Maria Callas in a TV movie and then became a household name playing the title role in her TV series Dr. Quinn, Medicine Woman. Kim Basinger had perhaps the most successful post-Bond career. After her break-out role in Never Say Never Again, Basinger went on to win an Academy Award for her performance in L.A. Confidential and to star in a number of blockbuster films, including Batman and 8 Mile, over the next two decades.  Broccoli's original choice for the role of Domino Derval was Julie Christie following her performance in Billy Liar in 1963. Upon meeting her personally, however, he was disappointed that she did not have the full figure he was looking for and turned his attentions towards Raquel Welch after seeing her on the cover of the October 1964 issue of Life magazine. Welch, however, was hired by Richard Zanuck of 20th Century Fox to appear in the film Fantastic Voyage the same year instead. French actress Claudine Auger was ultimately cast in the role. Thunderball launched Auger into a successful European film career but did little for her in the United States.  At one time it was said that appearing as a Bond girl would damage an actress's career. Lois Chiles is often cited as a case in point, even though her career did not suffer because of her portrayal of Holly Goodhead, but rather because, after she lost her younger brother to non-Hodgkin lymphoma, she decided to take a three-year break from acting, from which her career never recovered. Casting for the female lead in Casino Royale (2006) was hindered by potential actresses' concerns about the effect that playing the role might have on their careers. At that point, some thought that the Bond series had become stale and would therefore be a less desirable vehicle for young actresses. Nevertheless, the up-and-coming actress Eva Green agreed to play the role of Vesper Lynd, and showed those fears to be unfounded when she won BAFTA's Rising Star Award for her performance. Rosamund Pike, who made her feature film debut as Miranda Frost in Die Another Day (2002), went on to earn an Academy Award Nomination for Gone Girl.
