Remember when this kind of thing stayed secret? I'm not losing sleep over the production of The A-Team or anything, but it makes me nostalgic for the days down the long haul and into history back when you didn't know anything about secret cameos until you were in the dark theater. Then you could nudge whoever you were with and say "Oh my gosh! That's Dirk Benedict! Ha ha!" If you had your head bitten off when you started blabbing about the Zombieland cameo, this is the reason why. People like surprise cameos!
So, who do you think Benedict will be? Bradley Cooper's father? Someone helpful they meet along the way? One of the commanding officers coordinating the task force that's hunting them down? Or will Schultz, Benedict and Mr. T (you know he'll be the next one confirmed) all have a scene together where they hand over keys to the iconic van?
