Not Quite Human (film): Not Quite Human is a 1987 television film directed by Steven Hilliard Stern and starring Jay Underwood, Alan Thicke, and Robyn Lively.

Man Against the Mob: Man Against the Mob (also known as "Trouble in the City of Angels") is a 1988 NBC television movie directed by Steven Hilliard Stern, starring George Peppard, Kathryn Harrold and Max Gail.  "Man Against the Mob" is a precursor of the 2013 theatrical feature "Gangster Squad", in that it deals with the post-war formation of a special LAPD unit set up to suppress Organized Crime in Los Angeles.  It may have been inspired by the success of the 1987 theatrical feature "The Untouchables", a period drama which also depicted an elite law enforcement unit pitted against mobsters.  This was designed around the actor George Peppard as a tough LA cop in the late 1940s.  A 1989 TV-movie followup, "Man Against the Mob: The Chinatown Murders" is a sequel that also stars Peppard.  The first movie was a pilot of a proposed NBC series entitled "City of Angels" but ended up panning out as only the two TV movies before George Peppard died in 1994.
