I know it's just a movie & Hollywood can do whatever it wants(I like to state this in posts so miserable morons who like to feel superior to me don't have to point this out), but I have one thing about getting the alternate reality to work. It was the fact that some of the girls traveled to the Far East to learn martial arts & the Chinese & Japanese languages. Due to the fact that it would take about 2 years(4 years round trip) to sail to the Far East, plus about 2 more years to learn martial arts, customs, and language (depending how well someone learns), I figure it would take 6 years away from home. Throw in a few people who have trouble learning this & it becomes a real waste of time. Wouldn't have been easier to bring a few Shao-lin monks and other Far East martial arts teachers to England?
