"Rowdy" Roddy Piper. Not from They Live (though that would be cool too) but the actual wrestler. Two heads (long hair/smiling; short hair/serious) both with PERS, Hot Rod and Reality Check T-Shirts, Kilt, Bagpipes, full wrestling gear underneath. That's my dream Hot Toys figure right there. Hogan would be a very nice Hot Toys figure too, with all the different looks he's had (and again, even though we're talking movies here, I don't mean Mr. Nanny).
Movie wise I'd like a Marty Mcfly and Doc Brown. That would be great.
