Near the end of the movie, after they boarded the spider, Jim West (Will Smith) fight some henchmen of Loveless. When comes the turn of "Metal Head", Jim discovers that the guy is entirely armored and surrenders. "Metal Head" then raises his weapon to strike and... is electrocuted?
The way that Jim just calmly steps aside and lets the guy fall to his death tells me that it's what he had planned all along. But I really don't understand what happened. As far as I can see, he is not touching any kind of wire around.
Missing CGI? Continuity error? Or did I simply miss something?
