For a lot of comic book fans, hauntings and demonic entities are elements of the escapist fiction they absorb. For Zak Bagans, the creator and host of Travel Channel's Ghost Adventures and Paranormal Challenge, ghosts and malicious spirits are a very real part of his day. Bagans and his crew Nick Groff and Aaron Goodwin travel the globe in search of active locations as they seek to capture evidence of the paranormal on audio and video. Their methods of capturing evidence often include recreating an atmosphere recognizable to entities or even provoking them if they're deemed harmful to the living. We caught up with Bagans at Comic-Con for his take on his show, its approach and how what he and his team do relates to paranormal themes in wider pop culture.
