What a stupid thing to say. How the fuck would you know?
Also, they'd only need about 6-10 guys who are serious about weight training who can act AS COGS. Obviously you have not played Gears of War. This is not Othello. It's fucking blatant- huge bastards fighting a space war, all-action, chainsawing aliens heads off.
I am quite sure that even if 'most' BBers cannot act, producers could at least find 6-10 suitable guys who can convey the necessary emotions of anger/heroism.
Now please go back to where you were previously and keep your negativity to yourself. Like I said, please do not respond if you are not a fan of Gears of War.
On the positive side, I think The Rock would be a good fit for Tae. Tae seemed Kiwi/Samoan and I think The Rock's mum was Samoan? Anyway he was good in Welcome to The Jungle.
