These paintings were done by John Watkiss. He’s an amazing artist (http://johnwatkiss.blogspot.com/). I remember my wife and I went to his home when he was working on “World of Tomorrow”. The art was amazing. He makes it look so easy! I remember that was the day (probably spring 2002) when I first heard of “chem clouds”. He pointed out the peculiar clouds being formed by jet contrails. I’ve been looking up since that day and observed a lot of strange patterns in the sky caused by contrails. There’s a whole conspiracy on that subject with lots of evidence and speculation. Anyway, I don’t think he gets the amount of credit he deserves on many of his films.
