It seems Jude Law is on top of the wishlist at the moment. I could certainly go with Jude Law if I they are trying to get a younger actor. Jude is 31.
I'm not sure I like the whole premise of making Bond younger, though. Bond's always been a middle-aged guy. This smacks to much of the xXx sales-pitch: "This is not your dad's agent movie." To this I only have to reply "If it was good enough for my dad - it's certainly good enough for me."
Kind of liked Vin, though. Actually looking forward to Riddick.
