Notable guests are a hallmark of every David E. Kelley production, from Chicago Hope to Boston Legal (and beyond). The first season attracted Carnivále's Michael J. Anderson ("Mr. Dreeb Comes to Town"), Evening Shade's Michael Jeter ("Frog Man"), and Man of La Mancha's Richard Kiley ("Thanksgiving"). The series also features one of the last of the old-fashioned orchestral scores, Stewart Levin's distinctive piano theme. Picket Fences ran for four seasons on CBS (when Kelley left between seasons three and four, ratings took a nosedive). Afterwards, Combs joined Charmed, Baker joined Kelley's Boston Public, and Holly joined NCIS. --Kathleen C. Fennessy
