Chuck

Next week's episode of Chuck is significant for two reasons:

• Chuck is left alone at the base after Sarah, Casey and Shaw depart.
• The installment is directed by Zachary Levi himself.

Below, we've posted a behind-the-scenes look at Levi taking the helm, followed by a number of photos from "Chuck Versus the Beard."
