Laker Girls adheres slavishly to the formula established by those "Dallas Cowboys Cheerleaders" TV movies of a decade or so ago. We follow the progress of three aspirants (Tina Yothers, Paris Vaughn and Alexandra Paul) for the cheerleading squad of the Los Angeles Lakers. There's the standard "den mother" character (Jean Simmons), and lots of prattle about the dedication and responsibility required of each new Laker Girl. And of course, there's plenty of jiggle, which is why most of you tuned in anyway. Shari Shattuck costars as a Laker cheerleader who wants to use this job as the stepping stone for a superstar career--which actually did happen to ex-Laker Girl Paula Abdul, a fact driven home at every possible opportunity by the ad campaign for this 1990 TV movie.
