This coming fall, the PBS program Frontline will air a groundbreaking film on Parkinson's Disease, the degenerative neurological disorder that currently affects at least one million Americans. The filmmaker, longtime television and radio producer Dave Iverson, explores the story of this disease from many angles, ranging from the medical to the personal (Dave himself is in the early stages of Parkinson's) and the moral, wrestling as a Catholic with how he feels about the embryonic stem cell research that may hold clues as to how to cure the disease.

Here, you can explore clips from the program, which we will continue to update as the air date nears.
