Okay, this subset will probably land with a resounding thud, but I'll float this mental air biscuit anyway...
Made-for-TV movies. Before cable was all the rage the Big Three networks would put out movies for the public consumption. Most are obscure and old, but I'm a film buff, so over the years I've hunted down some of these and added them to the collection. I tried to exclude obvious TV pilots and mini-series. Some, like, "Duel" are classics by any standard. If you know of any, join in, the water is fine!
1.) Special Bulletin
2.) Birds of Prey (David Janssen vehicle)
3.) Trilogy of Terror
4.) Sole Survivor (1970 – Bill Shatner had a role in this one)
5.) Duel (Steven Spielberg made his mark)
6.) The Day After
7.) I Heard the Owl Call My Name
8.) Testament
9.) The Night Stalker * (ABC Movie of the Week, possibly intended as a pilot, but there was at least one sequel before it became a series)
