Last week, I purchased VEI's all-in-one DVD of a two-season (1974-76) NBC legal series called Petrocelli, starring Barry Newman as Anthony J. Petrocelli, a Harvard-educated Boston-area defense lawyer who left Boston and moved out to Arizona to practice in the fictional town of San Remo (the series was filmed in Tucson, AZ). Susan Howard co-starred as his wife, Maggie. I just earlier received that release of Petrocelli, and have captured Susan's co-title credit from that release.
And produced by Lenny Katzman! (Unfortunately, he left GUNSMOKE to do it, killing the last half of its last season).
Did not realize that! Also, Petrocelli was from Miller-Milkis IAW Paramount Television, and was one of at least two NBC series that I know of that the Miller-Boyett production family (Miller-Milkis inclusive) was involved in; another was Valerie, a 1986-91 NBC/CBS comedy (later called The Hogan Family) that originally starred Valerie Harper as the mother of three boys (she was there for only the first season's worth, then left in a dispute with the producers; she was replaced by Sandy Duncan as a surrogate mother to the three boys, IIRC).
