Imagine... Terrorists have a nuclear bomb on a boat in the harbor in Charleston, SC and are threatening to blow it up. 

Imagine that the whole thing is carried on live TV. 

Imagine that the whole thing was only a TV movie. 

That's what happened in 1983.  NBC aired "Special Bulletin" a TV movie produced to look like a live newscast. (Kind of like Orson Welles had done with "The War of the Worlds" on radio in 1938. *See Karen's blog*)

Check out the entire movie below.
