Bond films are composed of a simple formula that has stood the test of time: Hero, villain, ridiculously sexy Bond girl. In fact, most men will tell you that the Bond girls are what make the movies worth watching to begin with.

Out of the dozens of Bond girls, the list has been narrowed down to 5. These buxom beauties really stood out on the screen, and will forever be known as the reason why guys want to be James Bond.

1 - Honey Ryder. Played by Ursula Andress, Honey Ryder is perhaps the most mysterious Bond girl. Like a scene from a dream, Bond awakes to find Honey dripping wet, coming directly from the sea wearing only a scantily clad bikini and a knife.

Adding to the mystique, she begins to sing “Underneath the Mango Tree” as Bond looks out at this gorgeous girl. At the time of Dr. No (1962), Honey Ryder was the first Bond girl.

2 - Pussy Galore. Perhaps the least ambiguous name of the Bond series, Pussy Galore is an accomplished acrobat, who just so happens to be involved in organized crime. Bond saves Pussy from a crashing airplane after defeating Goldfinger, the two then make love under a parachute.

Galore makes an unforgettable Bond girl, simply by the incredible acting which Honor Blackman lent this role. At the age of 37 during production, Blackman was and still is the oldest Bond girl in history.

3 - Vesper Lynd. Played by the insanely gorgeous Eva Green, Vesper Lynd (though the film debuted in 2006) is the first-ever Bond girl according to Ian Fleming. In Fleming's original novel, Casino Royale, Vesper Lynd was the first woman Bond ever fell in love with.

After she betrayed him and was ultimately killed, Bond's heart turned to stone, and the character to follow would entertain only one-night-stand types of romance. Of the new Bond era (Brosnan and beyond), Eva Green is undoubtedly the most stunning Bond girl. Sorry Halle Berry.

4 - Anya Amasova (Agent XXX). The lovely Barbara Bach portrayed this dangerously beautiful Bond girl. Agent XXX from The Spy Who Loved Me is an agent of the KGB. Almost coming to blows in Egypt over a case of mistaken identity, Bond and Amasova end up traveling on the same mission, attempting to outdo one another.

When XXX learns that Bond killed her former lover, she vows revenge. Unable to pull the trigger after the mission, the film comes to conclusion with the two kissing in an escape pod while their superiors watch curiously.

5 - Wai Lin. Colonel Wai Lin is a spy for the Chinese People's External Security Force. Played by Michelle Yeoh, she proves to be a very formidable opponent for Bond. Her fierce nature and highly-skilled level of martial arts makes her more deadly than any previous Bond girl. The two encounter each other by happenstance on a mission.

Each believing that one was sent to kill the other; the two have a classic standoff. Eventually, they develop a mutual trust before ultimately being captured. Lin, able to resist Bond's advances, is the first Bond girl to do so.
