By the way, the fake promos for fictional movies at the beginning of that movie are way funnier than the rest of the film.
Jack Black, Ben Stiller and Robert Downey Jr.? How did they get anything done on set? Okay back to guessing. Kirk Lazarus: Wake Up Dead Man?
It's not literal, so it has nothing to do with soldiers, war, etc. Like I said before, that's Robert Downey Jr (the pic is not part of the game)
