The relatives of the enclosed people threaten to do whatever it takes to get their loved ones out. Warning Sign stars Sam Waterston, Kathleen Quinlan, Yaphet Kotto and Richard Dysart.

Ratings and reviews

saw this movie on television many years ago. Long before Sam Waterston was Jack McCoy. But the person I fell in love with was Jeffrey DeMunn, who incidentally has been a defense attorney at least once in Jack McCoy's Court. it's a great cast. and an underrated movie.

A movie dealing with method and subject matter ahead of its time.Viral and genetic manipulation are one of the more alarming threats to mankind since the advent of the splitting of the atom.

Saw it several times over several yrs. Great director great cast and crew
