Not going to lie. I've been in love with the War of the Worlds alien since the first time I saw it. And I always felt such pity for it when Dr. Forrester cleaned its clock and it ran away screeching. It would have been a great creature pet/buddy to have in the house. You come home from school and it's waiting there. You can read a book at night from the light of its tri-colored glowing eye.
Though I guess it'd have to live in a bubble. Common bacteria and all.
Found these GREAT photos on flickr. I had always assumed it was a smaller creature, and certainly not a costumed actor. I figured it was just a puppet.
