I honestly feel really optimistic about this. Bioshock was so story driven that I feel like it will have a real advantage over other video game movies. I'm definitely rooting for this movie. Since this project is so new there is no word on who will be cast in the main rolls. This being said I'd like to make a few suggestions.
Being that you mostly see only Jack's hand the whole game I'd love to see someone like James Franco play him.
And maybe Ralph Fiennes as Andrew Ryan.
How about Sean Bean as Atlas/Fontaine.
This one is a no brainer, Raychul as a Little Sister.
How about you? Who do you think should be cast?
