The One is a 2001 action film, directed by James Wong, director of Final Destination, and starring Jet Li, Delroy Lindo (wikipedia).
I was attracted to it because of its theme. A guy is trying to kill all the other versions of himself in various parallel universes, believing it will make him like a god.
A recording accident meant I missed a huge chunk in the middle, but in the end I did not feel I missed out. The film does not show much parallel universe jumping. It starts with the last other version of himself he needs to kill (I’d like to have seen more about various ||’s). I missed a chunk of the film then there was some action shots of them fighting which I put on fast forward.
Guess it is worth a watch if you have nothing better to do, but if you want to see more about the parallel universes it does not do enough.
