Dan Moran and Chris Jones are professional actors who share six decades of acting experience.

Now they share Parkinson’s disease, a progressive disorder that disables the brain cells that help control movement and balance. It affects all the elements essential to an actor’s craft.

They nonetheless put up an off-Broadway production of Samuel Beckett’s “Endgame,” a challenging piece of theater that makes the case that “there’s nothing funnier than unhappiness.”

“Endgame” is the story of Hamm, who is blind and cannot stand, and Clov, who can see but can only shuffle. They play out a vaudevillian routine of repetitive sorrow as they await the inevitable end to their diminishing lives -- a metaphor for living with Parkinson’s disease.

In “Me To Play,” we follow Dan and Chris as they take on this play, and as they navigate their lives, with all the difficulties Parkinson’s brings -- making dinner, riding the subway, going to the doctor, and living actors’ lives that can only take place in the heart of New York City.

Their physical and mental abilities are diminished. Their drive is not.

At issue in “Me To Play” is how their Parkinson’s disease affects their capacity to do what they love at the level they have always done it and expect to continue to do it.

By performing with Parkinson’s disease while opening their lives to a documentary, these two men show that they can meet even the most difficult circumstances with aplomb, senses of humor, and heart.
