It’s the best product placement for glasses since, well, Risky Business. In Mission: Impossible, Tom Cruise’s black wire-rimmed specs — equipped with a tiny camera — are a great complement to a peerless jaw. But spying the real-life eyewear — crafted without the camera for us civilians — will be nearly impossible. The frames, a $245 style from Jean Paul Gaultier, were discontinued early this year. ”There is a limited supply,” says a rep for Murai America, which distributes Gaultier. ”It won’t be produced again.” A missed marketing opportunity? The eyes have it.
