So I'm kidding about the Tony Stark thing... but that was the first thought that popped into my head when I read the description for Crank 2: High Voltage in which Statham's character:
"...faces a Chinese mobster who has stolen his nearly indestructible heart and replaced it with a battery-powered ticker that requires regular jolts of electricity to keep working."
That's outrageous enough to fit right in with the first film. So they replace his heart... what do they do with his actual heart while he has the fake one in his chest? Keep it on ice? I suppose this will add to the adrenaline pace of the movie by requiring him to complete whatever task in a very limited amount of time in addition to always being on the lookout for a recharge of electricity.
If it's anything like the first one it'll be a wild ride with no pretensions of being "high art," but it will be a lot of fun. :-)
There's no target release date set yet for Crank 2: High Voltage.
