Intense (''Gears of War''), goofy (''Bad Dudes Vs. DragonNinja''), offbeat (''Mega Man''); adapt these, please!
The Story: A plane crashes in the middle of the Atlantic Ocean, and the lone survivor finds himself in the underwater libertarian techno-utopia known as Rapture a once-great city descended into anarchy.
Our Cast: The mysterious main character of BioShock doesn't talk too much and seems variously innocent and sociopathic; we'd cast Jeremy Renner and let those blue eyes do the talking. The real key is casting the right actor to play mid-century science visionary Andrew Ryan, one of the greatest characters in videogame history. How about Gary Oldman?
Why It Might Not Suck: Set in a gorgeously designed retro-future world, BioShock is a visual wonder. And since since the society of Rapture is based on the philosophy of Ayn Rand the always-topical, always-controversial writer of Atlas Shrugged a BioShock movie could turn into a Nolanesque movie that combines big action with big ideas.
