Is not totally the same thing, but has the same aspects of it..."we" found a way to "jump" to other universes (i think there are 153 total) and each universe is just like the next, but with a few changes (ie: Gore for president instead of Bush) and there are different versions of us on each too (ie: your *** in one or in prison, etc..)... you warp to other universes by sitting on this chair and someone in the next room selects the coordinates....
You gotta see it! its pretty sick!

oh and the story is about a guy (Jet Li) who finds an easier way to warp to the other universes, and he kills the other version of himself, which somehow makes him stronger with each version of him he kills (ie: he can pick up motorcycles, jump high, run supper fast)....i dun wanna give away too much so ill stop now...
