Well one of mine must be 28 days later, but i don't know why. Then i have another one, but I don't know hte title......It's about the whole world is underwater and the protagonist ( I forgot the name) has some dry earth and sth....sth.
I think that was Waterworld with Kevin Costner, not a bad film but I believed it flopped for some reason (either flopped or cost so much it never made the money back). Personally I thought the bad guy was the best character in that
