Andrew and Tonya Keyser began researching paranormal phenomena for a book project, only to toss the idea when they felt a book would be too dry. They turned their focus onto making a film, which they called The Other Side: Giving up the Ghost. The 80-minute documentary contains interviews with people who run or attend ghost tours, paranormal research teams, paranormal organizations, skeptics and psychology experts. It was filmed mostly in Gettysburg over the summer and fall of 2006. Other locations include Allentown; Amherst, N.Y.; Philadelphia; Richmond, Va.; and St. Louis.

There are a great number of people Adams County who are interested in the paranormal. However, Tonya wasn’t sure if this interest is because they experienced paranormal phenomena or because they are seeking to experience such phenomena. This was one aspect she and her husband covered in the film, which is due for release in DVD format on May 1, 2007. They will sell this DVD directly from their website, but hope to sell it on Amazon soon.
