Kotaku supposedly got their hands on a private-ish casting call for Portal 2 that was put up at the industry-only site, Breakdown Express. The casting call, which can be found linked below in thumbnail form, calls for an actor to play "Cave Johnson" in Portal 2 (pictured right).

He is a man in his early 60s, is the founder and CEO of a "successful applied science company, a self-made billionaire who's learned to trust his gut and doesn't sweat the details, [and] is a big picture thinker." The casting call continues on to describe him.
He might not know how science works, but he knows how people work. used to getting what he wants. Extroverted, enthusiastic and opinionated. High energy: life is an adventure he's happy to be on. A born salesman, a leader, an evangelist. People trust him, even when his plans are clearly dangerous.


The call continues on saying that the character goes from sidekick to "principle antagonist" (emphasis is mine). As time progresses, Cave starts to "lose his grip on his humanity" and proceeds to "isolate himself from the people around him [and] he loses touch with reality."

If this is at all true, this is the very first morsel of Portal 2 news that is known publicly. All images and information come courtesy from Kotaku.

Kotaku once again wrangled up a few more details about Portal 2, Cave Johnson, and well... Read on. Beware, there are spoilers contained below! These are potential, real snippets from the dialog for Portal 2.

You've been warned.
The script samples we saw for the Cave Johnson role indicate that the Aperture CEO and "eccentric dead billionaire" is, well, already dead, living on in simulated computer form. He tells an unnamed rookie test subject via loudspeaker that "As of this mornin' yer old buddy Cave has been resurrected inside of a computer. And I never felt better!" acting as this entry's GlaDOS - possibly that prototypical GlaDOS, as theorized earlier - encouraging the player to continue the testing while waxing philosophical about the afterlife.

"I been thinkin," the script reads, "Heck, suspended as I am in this inky purgatorium, I got nothin' to do but think. What if them engineers didn't do me no favors pourin' me into a computer? What if they denied me my final reward?"
Is your mind blown yet? Is it? Mine is. I cannot wait to give Portal 2 a spin now with an AI that is voiced by an eccentric, dead, southern billionaire.
