I had thought so as well, but this seems to be more of an action film then a martial arts one Jet Li is known for. Might be worth a look, if only for Jason Stratham. Jet Li like so many other Asian martial artists, lost a lot of their appeal when Hollywood came calling much prefer his earlier stuff.
Sly Stallone is right. Jet Li said he will not be making anymore martial arts period films. That dosen't include the use of martial arts being non exsistant in his films beyond 'Hero'. That film War looks pretty good though.
