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?
Question: I'm still a bit confused on the tripods' actual height. I can't find it anywhere and I just wanted to make sure how tall the tripods are. Preferably in meters but any measurement is fine.
Question: Why do the tripods make a horn sound?
Question: At the end, a tripod collapses after behaving erratically for an hour, because the aliens inside were dead or dying. If so, wouldn't the tripod just stop moving and stand there because the aliens were too sick to operate it?
Question: How come the grandmother's house was not attacked while the tripods were taking down every neighborhood.?
Question: Do we know the human casualties by the end of the war?
Question: Is it realistic to think that Manny, the garage mechanic would have NO idea of what was going on when Ray steals the van from him? After all this is probably about 20 minutes after the Tripod emerged a few blocks away. Surely news would travel faster than that! And you'd think Manny would have felt the massive tripod moving or heard the destruction.
Question: When Tom Cruise is battling to get free of the tentacle pulling him into the ship from the cage, there is alien (presumably) writing visible on the underside of the tripod just beyond his arm and above the lights. Can someone shed light on what this may say (theories, previously suggested writer/director thoughts)?
