Continuity mistake: On the ferry, Rachel wears the purple/pink camouflage hoodie over her orange knit sweater with the colorful stripe sleeves, as usual. Now this is where things become strange. In the first shot as the trio come ashore, she is only wearing her orange sweater, she is not wearing the purple/pink hoodie - note the clear lack of fur hood. In the very next shot as they climb a bit more and then rest, Rachel is wearing the purple/pink hoodie - note the hood, but now it's on under her orange sweater. In the underwater shots she is also wearing it under the orange sweater. (This odd mistake has absolutely nothing to do with the very long wool cloak that Rachel wears in the next scene).

War of the Worlds (2005)
Plot summary
Directed by: Steven Spielberg
Starring: Tom Cruise, Tim Robbins, Dakota Fanning, Miranda Otto
Ray Ferrier (Tom Cruise) is a working class man living in New Jersey. He's estranged from his family, his life isn't in order, and he's too caught up with himself. But the unthinkable and, ultimately, the unexpected happens to him in an extraordinary sense. His small town life is shaken violently by the arrival of destructive intruders: Aliens which have come en masse to destroy Earth. As they plow through the country in a wave of mass destruction and violence, Ray must come to the defence of his children (Dakota Fanning and Justin Chatwin). As the world must fend for itself by a new and very advanced enemy not of this world, its inhabitants must save humanity from a far greater force that threatens to destroy it.
Trivia: In an early scene in which Rachel is watching television, she's channel surfing. At one point, she hits briefly upon a shot of a car being demolished by a speeding locomotive. This is, in fact, a scene from "The Greatest Show on Earth," which Steven Spielberg has reported as the first movie he ever saw at a movie theater.
Question: Several other answers and corrections state that the reddish liquid sprayed by the tripods was what essentially grew the red vines. However I thought I heard someone in the film say something along the lines of "using us (i.e. blood) as fertiliser". Can someone please clarify?

Answer: Since the tripods tended to spray the red fluid shortly after pulling a human into themselves, it seems a good assumption that the red fluid is essentially blood. Given this, it seems likely that the "spore" of the vines is spread in the red fluid.
