Quoted from Jesterfunhouse:Gravity!!! 3D pinball...Plus the whole movie is about completing one hard task after another with the clock ticking...lots of cool possibilities...
PLUS lots of funny George Clooney call outs...like in the movie...guideing you along...
That's so weird that you mentioned this. The day after I saw that movie I had zero gravity on the brain big time and 3D pinball totally crossed my mind.
