4. Brain Age

In this ad for Nintendo’s Brain Age, we see actress Liv Tyler dressed formally, but she still appears to be enjoying herself in a bed while playing Brain Age on her Nintendo DS. And probably many fans of the world-renowned actress were disappointed not to see her in a sexier outfit, but her rather formal attire here is fitting considering that Brain Age is a game designed to exercise your grey matter.

So Nintendo did not resort to scantily-clad ladies as in other ads for the Wii or games like Bayonetta. But actress Liv Tyler, who exuded sexiness in her role of Arwen in the Lord of the Rings Trilogy, proves that class and good looks are enough to make an ad sexy, without resorting to bikini-clad women with curvy physiques.
