Speaking of Darth Vader, guess who this big guy is? That's right, none other than David Prowse, the man behind the obscidien mask. It's hard to tell because there is nothing in this photo to get a context of his size from, but this guy is freaking huge! I mean, you should see the size of the guy's head! I have a pretty freaking huge head myself but you could fit one and a half of my heads inside David Prowse's head. He's huge! HUGE!
