Its not like he is going for an oscar here. He is playing a slasher in a horror movie. It could end up being pretty good. Although I think it will probably be another bad slasher flick. If it wasnt WWE, it would probably be straight to DVD.
If I was marketing the movie, I probably would not even credit Kane in the previews. To get away %100 of the WWE stigma, like Kable said.
What movie is Cena doing?
btw, I have to say The Rock has been suprisingly effective and entertaining in the movies he has done so far (save Scorpion King and Be Cool). He has great screen prescence like Shwartzanegger. I thought he was a little dissapointing in Doom, but it was still a fun flick.
