Couple of Bits on Year One

I've been waiting for a quiet moment to do an update on The Year One which is currently filming in San Diego. There's not a huge amount to report but Peter Chattaway did pick up on a report from ComingSoon.net which notes that comedian David Cross will play Cain. Peter can't help but note the potential historical anachronism. I was under the impression that this might be something of a journey-through-time affair anyway so I'm not too concerned about this at this point (not that historical anachronisms in a Jack Black comedy are particularly concerning in the first place). Having said that I'm not sure where I got this impression from. A quick search through my other posts on this film failed to turn anything up, other than the fact that Jack Black mentioned Cain in an MTV interview.
