With their new ad campaign, Burger King is clearly trying to cash in on David Beckham's celebrity status in order to give them a hipper, more exciting image, after years of using the family-friendly "Burger King" as the center of their advertising. Interestingly, Beckham's image in the US is quite different from his image abroad. In America, he is known more for being good-looking and famous (and being the husband of Posh Spice) than he is for playing soccer, which means that he has a different demographic of followers here that Burger King is trying to reach. I would guess that most women anywhere from 15- 40 years old recognize Beckham from seeing his picture plastered throughout celebrity magazines like People Magazine, whereas most men over the age of 30 who don't follow soccer are probably unaware who he is.
Using their positive associations with Beckham's celebrity popularity, Burger King is hoping to make itself "cool" in the minds of young to middle-aged women, which will hopefully make them consider stopping in. After all, when someone like David Beckham, who could afford to eat at the most expensive places with all his celebrity friends, is ordering at the counter from a Burger King, it might make people rethink their feelings about Burger King as a cheap family-oriented food place. At the very least, this audience will be drawn into the ad because Beckham's face is featured prominently, which draws their attention to Burger King for thirty seconds. And because the viewer is watching the ad, they will also see the making of the "delicious" fruit smoothie that is subtly wedged in between Beckham close-ups, allowing the viewer's positive associations with Beckham to carry over to the fruit smoothie.
Perhaps even more than it is an ad for Burger King, this is an ad for the David Beckham brand. Although he has long been tabloid fodder, Beckham really doesn't really have much of an established public personality for better or worse, which means that most viewers can't really connect with him or "like" him as a person. That Beckham is willing to be in a Burger King ad, and especially when he is making fun of his image as only a pretty face, gives him a sense of humor that viewers can connect to, and ironically makes him more than a pretty face. And by establishing a more personable side to Beckham, he makes himself more marketable, which in turn helps Burger King's ad campaign as well. Probably a win for Burger King, definitely a win for Beckham.
