The Omega Man

“The last man alive...is not alone!”

Nobody else in the city is alive in the daytime, yet every night a few hundred pale, light-sensitive people gather outside the building where Robert Neville (Charlton Heston) has barricaded himself. A bioweapons war has killed nearly everyone, and an experimental vaccine is the only reason he is still breathing. Boris Sagal leaves him alone in the sun with a rifle, then shuts the day down and leaves him waiting for dark.
