Ask Prosser about head.

BBC airs some behind-the-scenes footage from Hitchhiker's Guide, which includes our first looks at Arthur (Martin Freeman), Ford (Mos Def), Trillian (Zooey Deschanel), and a big-hair Zaphod (Sam Rockwell)...They all look good, although I was thrown by Zaphod's lack of second head (Apparently, it's in his nose...yeah, I don't get it either.)
