Script A-Like

I recently had the chance to see the film I Am Legend.
After all the publicity I really wanted to see what all the fuss was about.
Well, it was a big surprise to see that the story was almost a copy of another film I had seen a few years before. Remember 28 Days Later? Danny Boyle?

Did anyone have the feeling we were watching the same film again? I did.
Let’s review, shall we?

I Am Legend
Dr. Robert Neville (Will Smith) drives around the ghost-town of NYC.He is the only survivor of an epidemic that devastated an entire city, country or planet…?

28 Days Later
Jim (Cilian Murphy) wakes up of a coma to find himself alone in a hospital, city, island, planet… He is the only survivor of an epidemic.

Both characters in both films run from the only other people that share the cities with them. The Infected. In both films, the virus is rabies. Of course, the action is all about these escapes and near death (infection) experiences, meeting un-infected, thought unexisting (but then where would the films go?) people on the way.

So, anyone see a resemblance?
