Mr. Cavill has the dark curly hair that Esben has. He most certainly has the charisma and charm and I think it would be great to see him in a more sinister role.
Since the character is East Indian he would need a tan but I'm sure that won't be a problem. I would be open to someone out of Mumbai so please send me your nominations.
As a bonus I have found his cohorts Nolin and L'heilh. Nolin is the head of security and L'heilh is Esben's assistant. They are together constantly, as hosts often are.
Callum Blue is English so we won't have to worry about his accent. As General Zod we know he can be mean when he needs to. And as Mason from Dead Like Me, we get the manic smart ass.
Rebecca Romijin for L'heilh is a great choice because she can play both elegant and deadly as the need arises. And she is no push over, do not mess with her.
