One that I personally happen to like is the TV-mini "Storm Of The Century". IMO, a much better better result than a lot of the Stephen King material that's translated to TV (whether or not he handles the teleplay duties, as he did with this one; some of his others have been pretty lacking, IMO).
This one just happened to be on my mind, since it was on SciFi this past weekend. That prompted me to pull out the DVD on a dreary Sunday evening...perfect atmosphere for this one.
Don't know if my choices "count" as movies, but I've always been a great fan of North and South. Sadly, my other two favorites, Queen and A Woman Named Jackie have yet to see DVD releases.
The two telefilms, The Night Stalker and The Night Strangler, starring Darren McGavin as nosy but loveable reporter Carl Kolchak, are available on one disc from MGM. Fun stuff!
The Stand, hands down. The Day After is a great old movie. I bought Threads off ebay, but wasnt really impressed with it. I own it, I'll try watching it again someday in hopes that I wasnt in the right mindset the first time I watched it, but for now I cant recommend it.
Note- Threads is basicly the British version of The Day After.
Another vote for "The Stand" here...though I'm still waiting for that groundswell of support for the release of the 1980 gem "The Ordeal of Dr. Mudd." One of the best films made about the Lincoln assassination, IMO.
"Duel" I think has to win the award for best TV-movie on DVD hands down.
Confining this category to TV movies no longer than four hours (two parts), I would also add "The Missiles Of October" (1974), "Rehearsal For Murder" (1982), "Hiroshima" (1995) and "DC 9/11" (2003).
Most of the 1980s nuclear war films don't hold up well IMO, because they were made for reasons of an underlying political agenda that was proved wrong by subsequent history.
I would also agree on "61*" being an outstanding TV movie on DVD. Another good one that is unfortunately only available as a cheap PD DVD release is 1986's "The Last Days Of Patton" with George C. Scott reprising his most famous role.
Another good TV movie of Scott's available is the 1984 "A Christmas Carol".
There are alas many good TV movies of the 60s and 70s, the days when such movies were really a special kind of event on television, that I fear we may never see on DVD because they have become so obscure.
I'd recommend "44 Minutes: The North Hollywood Shootout" which aired on fx about a year ago. It's based on a true story about two men who attempted to rob a Bank of America branch located in North Hollywood using AK47's and the ensuing shootout with the LAPD on February 27, 1997.
