I'm mapping through all the concepts I need and try to grasp, at least, basic knowledge about it. It helps I'm math literate (to an extent), but I still have a long way to go before I have a believable premise (+ a magic/unknown factor to make an interesting story) before I contact an expert in information theory to make it even more believable. I suspect this will be the king of "nerd" movies, but I don't care - it's something I would watch, that is all that matters for that project.
