So that's why...

Do you know how CGI works? They're trying to make it realistic

I used to do a lot of editing and cgi actually, the head probably had to be covered with a solid color to key out the area underneath her hand but I don't see a reason why he had to wear the entire suit, it's not used for motion tracking or chroma keying

i woulda put a dog in the suit she woulda pet it for it real.
