Valve is recruiting voice actors for Portal 2, and the
first details have come to light through industry site
Breakdown Express. Valve is looking for somebody to voice Cave Johnson, 60 year old former boss of Aperture, who will be a principle antagonist, labeled as an out of touch with reality sidekick. As Mr. Johnson is actually dead, this may indicate that Portal 2 is set before the catastrophic conclusion of the original. Being a 'dark comedy' the role requires comic timing, with dramatic moments.
