"Hot in Cleveland" is hoping its new casting gimmick will turn the world on with a smile.
The TV Land hit, which was recently renewed for a fifth season, is staging a reunion of "The Mary Tyler Moore Show" cast for an upcoming episode, with Mary Tyler Moore, Cloris Leachman and the ailing Valerie Harper (all in photo at left) joining forces with "MTM" alum and "Hot in Cleveland" star Betty White and recurring cast member Georgia Engel.
