I remember watching a movie on TV — during the 70’s.  I am not sure what happened to the town but it seemed that only one man was alive and he had a super fast sports car.  He was wandering through town one day, looking for food and stuff and all the people were frozen in time/I guess dead.  There was one women, African American who was still alive and when she saw this man wandering through town, she froze — so she was still like the rest of the dead people.  The two ended up together.  At night they had to lock themselves into his apartment because there were some kind of “army” (not sure) looking for survivors.  It was a really weird move but for some reason — I keep recalling it and I have no idea what the movie was named.
