ah, the elves coming to reinforce the defense of Helm's Deep ... just forgot the elves, being concerned only with the books, not the movie ... (well, I should have foreseen that, and kept my mouth shut!)
... the issue of how the Elves in the movie reached Helm's Deep before Saruman's army.
... complicated issue, because the storyline must not be in conflict with the books, so there are some conditions and movements to be sorted out (well, it is done - it just takes some time to write it all, and right now I'm just as much in need of time as Gandalf was, meeting the 3 hunters in Fangorn Forest)
conclusion (without details, arguments or timetable): DON'T LOOSE HOPE!
The elven reinforcement from Lothlorien WILL come to Helm's Deep, but only JUST before the dike are attacked by Sarumans vanguard ... (I guess that is also how it really SHOULD be) ... the elves have to march fast for five days and nights (barely resting at night) and they have to equal the speed of Ugluk's Uruk-hai, which IMO is quite possible.
... details later ...
