After spending a day on the set and chatting with Glenn Close, I was even more excited to see what season four of the always engrossing “Damages” has in store for us. And while this is only a taste of the terror to come, it certainly paints a chilling portrait of just how in-depth the show while examining PTSD through Chris Messina’s character.

Earlier this year, Chris explained to PopWrap just how seriously he was taking this performance. “I’ve stayed up two days in a row because guys with PTSD don’t sleep, so I stayed awake for 48 hours, drank some Red Bull which made me real shaky and went right into the scene. Now that’s either going to really work or really not.”

From the look of this trailer, it’s the former.
