Are you talking about the Redford-Gandolfini military prison flick? I don't think it's a HBO film, if that's the one you're talking about. It was released on the big screen in late 2001...great flick, though. I'm not normally a Redford fan, but he did a good job in it.
Scouts Out! Cavalry Ho!
I was working the ramp at John Tune airport which is right behind the old prison when they filmed it. They flew the choppers in to fuel them and would give us a ride every now and then. They tried to buy the Huey at the mechanic's school I was attending but we wouldn't let it go (we used to secretly fly the thing in the field behind the school).
