Here's Randy's Full Quote:
"Amazing how loud a 50 cal machine gun is ! Let the games begin . Expendables 2 is rolling :)."
I've been informed by Dolph Ultimate that Randy's quote may have been a bit misleading, its still likely just the stunt men doing initial prep work that are filming right now and the actual actors likely don't start for a few days yet. But either way, actors are beginning to arrive, things are in motion, Expendables 2 is on its way!!
