Slowly but surely, Ryan Hardy (Kevin Bacon) is closing in on Joe Carroll (James Purefoy) on Fox's The Following. But that doesn't mean he won't face more than a few obstacles on the way to confronting his nemesis.

On Monday's episode, Ryan found himself involved in a warehouse shooting with two of Carroll's acolytes. "The more the danger level rises, the more fun the gun battles get," admits star Sam Underwood, who plays sadistic twins Mark and Luke. "My inner 5-year-old is going pretty crazy right now."

Check out the videos below, exclusive to, to hear Bacon, Underwood and members of the crew talk about the intricacies of filming action scenes like the one in Monday's episode — and to get a behind-the-scenes perspective at the "cat-and-mouse" power struggle that's happening between Joe and Lily Gray (Connie Nielsen).
