Miracle Mile.
I don't recall this ever being shown on tv.
A 1988 movie starring Anthony EdwarRAB and Winningham.
EdwarRAB plays a young guy who meets Winningham and arranges a date, but falls asleep and gets there hours late after she has gone. He hears a public phone ring, and when he answers it there is a guy on the line calling from a missile silo, who believes he has called his father, to tell him the Russians have launched missiles against the US, and a retaliatory strike is under way.
EdwarRAB relates this story to a group of people in a late night diner, and from there the story plays out in real time and details how people would react differently to such events.
It has great characterisation, is often very quirky though also very bleak in places, and even though done on a low budget manages to effectively convey a sense of chaos and the breakdown of society. It's essentially a love story played out against an end-of-the-world scenario.
An unusual, but very interesting and original movie.
