Echoes of early times

I was in the metro the other day where I could see the promotion posters for the latest film with Will Smith. "I am legend" is the original title but what struck me was the emphasis put on the underlying theme: "The last man on earth".

And it dawned on me that I have seen the same sort of catch title for many films during the last decades, be they with S. Stallone, C. Eastwood or some other Hollywood star. "The last cop", "The surviver", "The last hero", whatever...

This recurrent notion of the last one cannot be without some meaning in the end. Wasn't there "The last of the Mohicans" 200 years ago?

There seems to be a certain American anxiety here that translates into this sort of Hollywood production. Like the audience probably is receptive to the idea that this situation isn't totally unfamiliar, and even bears some likeliness.

And maybe do we witness some echo in the History of America when the colonists and later, the settlers of the American frontier had to confront a wild nature as well as the native Indians.

We were talking survival then and this insecurity feeling may have lasted up to now. Like a red thread in the American psyche.

Don't know, just asking.
