Here's what surprises me most about T-Mobile's dropping Catherine Zeta-Jones from its ubiquitous ad campaign: that the woman in those ads was actually Catherine Zeta-Jones. I had always thought that the company had hired a look-alike after using C.Z.J. in the ads' initial blitz in 2003. I considered that strategy to be brilliant: customers subconsciously think this no-name model is this top actress. I thought the "model," however, never looked as attractive as C.Z.J. And I couldn't imagine an actress identifying herself so closely with a corporation for so long. Now that C.Z.J. is out, I guess she'll have to start actually acting.
