The actor was particularly interested in how having spider DNA making up a percentage of your blood would change a person.
“So I studied spiders, I studied their movements and how they operate in the world and I tried to incorporate as much of that as I could. He’s a boy/spider in terms of how he moves and not just in the suit,” Garfield told the
Los Angeles Times
He also said being part arachnid would shape the way his character interacts with people because a spider's skin is very sensitive
“That’s the thing with the spider sense and the way he takes in everything. Imagine all of your skin was as sensitive as a spider, the slightest gust of wind would feel like a tornado going by. You’d always be rushing, that rush. What does that do to you? The idea of how he adjusts to that,” he said.
Garfield even admits he thought about what it would be like to have more legs and arms.
“A spider moves up, down, side-to-side, all around. He’s not linear and with the knowledge of that spatial awareness and the fact that he can be here and then over there incredibly fast. The stillness of a spider and the lightness I found all of that very interesting to explore as well.”
