My students do this all the time, they want to get a star or comedian to star in their campaign and I stop them dead in their tracks. Because - unless there is a major reason why the star needs to be part of the ad - the star will end up a phagocyte to the creative/conceptual effort. Just like the ad above.
The only thing I remember is Elissa. I don't even remember her contact lenses! And of course, certainly do not remember the name of the brand of contact lenses....
