Warrior Forever
Daniel Craig
The man has the look and the body, and he could do really any gimmick he could come up with considering his ability to play so many different characters so well. I could really see a guy like him with those cold blue eyes following the path of Randy Orton, he could play a calculating beast that the fans would love and his opponents would fear.
One other I would like to mention is Jason Momoa, as he showed in his recent film "Conan", he can play a badass and he can definitely kick ass. He has a look that would fit him in the WWE quite well, I would think he would be like Tyler Reks but more appealing, he could even be billed as a Somoan or possibly tie him in with the Usos as an enforcer.
Lastly I do like the idea of Hugh Jackman, I think he's got a good look for it(kindof reminds me of Trips) and he's shown that he can throw a punch.
