As a kid, my mind sort of tied together three Charlton Heston movies that were on TV a lot in the mid 70's as coming from the same tree.
Planet Of The Apes
The Omega Man
Soylent Green
Each had the hapless Chuck Heston dealing with 3 versions of the end of the world (though it took until the end of POTA to figure hay out completely).
Chuck sure had it rough
