Granted, I have never played Duke Nukem and have only seen videos, but damn, that’s a pretty good casting. Cinema Blend has confirmed Cena for the role. Cena himself is not know for being a spectacular actor, but he is capable of much more. Also, the character of Duke is not exactly an Oscar worthy performance either. So I think he should do well. The movie is being produced by Platinum Dunes and there is no script that has been made as of yet. So this could be quite a while before we see Duke on screen.
