While execs at the Fox network long ago learned that people have a strong desire to watch shows aimed at an audience of gore-hound rubberneckers (think, America's Most Shocking And Deadly High-Speed Rollover Accidents Part Six), the folks at the more family friendly American Broadcasting Channel rolled the dice when they cast the last season of Dancing With The Stars. Their bet was that they could appeal to an under-exploited niche of the American television viewing audience by casting a one-legged former trophy wife of a Beatle. After all, would people really tune in to see whether or not she would fall on her ass while doing the Cha-Cha? Not surprisingly, they did tune in ... in droves, even. So when it came time for this season to roll around, producers decided to go right back to the developmentally-challenged well when they decided to cast the hearing-impaired Oscar winner (and stone fox) Marlee Matlin.
