Can anyone think of good "Last man on earth movies" or movies that involves basically a person alone Here is a brief list of some I can think of:
Castaway
I Am Legend
The Last Battle
The Omega Man
Planet of the Apes (everyone was an ape or a really downgraded cave human)
The Last Man on Earth with Vincent Price is actually the first version of Richard Mathison's I Am Legend, and is much truer to the storyline. Also, if you like zombie movies, then I can recommend 28 Days Later.
The DVD that NetFlix has of The Last Man on Earth includes a double feature called "Panic in Year Zero". It's about a family trying to survive after nuclear war wipes out LA, and it's got a lot of good commentary on the break down of social order and what people will resort to.
How about John Carpenter's "In the Mouth of Madness". It took most of its inspiration from H.P. Lovecraft stories. "The Quiet Earth" is another classic.
Many of the original Twilight Zone episodes had last person on Earth type themes. Some are last people, rather than last person.
Where is Everybody? (the pilot episode)
The Lonely (the 1st regular episode)
Time Enough at Last (a true classic, I strongly recommend it)
People are Alike All Over
I Shot an Arrow into the Air
Elegy
Two
The Midnight Sun
On Thursday We Leave for Home
A Kind of a Stopwatch
Stopover in a Quiet Town
Probe 7 - Over and Out
On Thursday We Leave for Home, is that the one with the burning hot sun and the guy who considers himself a leader of his people? He runs the roost so to speak and they are supposed to get on a ship to finally take them home?
