Schwarzenegger vs. Schenkenberg in "Terminator 4"?
One source indicates that Dutch/Swedish actor-model Marcus Schenkenberg could very well be the title character in "Terminator 4," if and when the project ever gets off the ground. The guy's only been in a few movies and TV shows, but apparently he's really hot and buff and all that stuff.
The same source also offers this: Ahnold is scheduled to make a brief cameo in the third "Terminator" sequel.
Take it all with a grain of salt, of course. But stranger things have happened.
